This city is already advanced in technologies providing the futuristic level of hardware designs. If you are looking for servo voltage stabilizers your search ends here.

INTRODUCTION: -

Voltage stabilizers are used to stabilize or regulate the voltage if the voltage is fluctuating over a given range. The main purpose of stabilizers is to provide a constant voltage to load or appliances.Servo Stabilizer is a Servo motor driven stabilization system that performs optimum voltage supply.

Servo stabilizer is an electromechanical device therefore its voltage correction speed is slower than static voltage stabilizer.

Following are the two types of servo voltage stabilizers

• Air-cooled Servo Voltage Stabilizers
• Oil-cooled Servo Voltage Stabilizers

Air-cooled Servo Voltage Stabilizers:

Air-cooled Servo Voltage Stabilizers are very much useful for various electrical as well as electronic applications.The servo stabilization mechanism with air-cooling means efficiently ensures optimumvoltages.This stabilizer includes a transformer and a power control circuit for controlling output AC voltage. The negative feedback circuit controls the voltage or power automatically and regulates it to a level that’s set or required. The most effective part is that within the entire operation, the voltage regulator doesn’t require any manual interruption, it functions automatically.

Oil-cooled Servo Voltage Stabilizers: -

Oil-cooled have inherently higher short-time or sustained overload capacity as compared to Air-cooled types. The main difference between oil-cooled and air-cooled stabilizers is the capacity of oil-cooled stabilizers are for higher capacity. These are used in places where there is a high frequency of fluctuating voltage in the power supply. Anoil-cooled stabilizer guarantees that the fluctuation in the power supply does not affect the electronic or electricaltypes of equipment.

Chennai city is leading in the hardware industry. From the past few years, it has advanced alot in hardware technology development. Foremost Nantech Power Systems Pvt Ltd., one of the most important major hardware manufacturing companies that provide top-level transformers.

Constant voltage transformer: -

Constant Voltage Transformer (CVT)is a non-linear transformer also known as Ferro resonant Transformer (Ferro).

Ferro resonance is a regulated voltage output provided by CVT through an electromagnetic phenomenon.

CVTs are basically 1:1 transformer that is excited high on their saturation curves, thereby providing an output voltage which isn’t significantly tormented by input voltage variations. This special characteristic is that the foundation of the appliance of Ferro resonant transformers as power conditioners.

Ultra-Isolation Transformer: -

An Ultra isolation transformer is a transformer that’s accustomed transfer electricpower from a source of alternating current (AC) power to some equipment or device while completely isolating the connected device from the power source, usually for safety.

An isolation transformer is a transformer, usually with symmetrical windings, which is used to decouple two circuits. An isolation transformer allows an alternating current(AC) signal or powers to be taken from one device and lead into another without electrically connecting the two circuits. Isolation transformers block the transmission of direct current (DC) signals from one circuit to another, but allow AC signals to pass through. They also block interference caused by ground loops. Isolation transformers with electrostatic shields are used for power supplies for sensitive equipment like computers, Lab Instruments, CNC Machines, Medical Equipments, etc.

Isolation Transformer employs a novel multiple shielding technique that reduces the inter-winding capacitance to a large extent and increases the DC isolation.

First important factor for a person while choosing an inverter is to check the power (in Watts) consumption. The following link maybe of help - https://www.vguard.in/product/product-power-calculator

Volt- Ampere (VA)- It is a unit of electrical power in a (electrical) circuit.
650 VA is 520 Watts;700 VA is 588 Watts etc
(1kVA is 1000 VA)

What are tubular batteries?
Tubular batteries are also known as deep discharge batteries is a lead-acid battery. They provide a small amount of current, for example, 5 Amperes, for a long period of time. The electrodes of these batteries are thicker than the regular ones and hence cannot release a large amount of current. Moreover, they cannot be used in domains where a large amount of current is required in a relatively short period of time. Although they don’t provide high current, they last for a longer duration as compared to regular flat plate batteries.

WHAT ARE THE DIFFERENT TYPES OF TUBULAR BATTERIES?

Nantech Power Systems provide a multitude of tubular batteries:

• Exide
• SF Sonic
• Luminous
• Rocket
• Okaya

As there are several options, we have provided a brief yet comprehensive comparison of different tubular batteries that you can choose from.

Conclusion

To conclude, when you decide to purchase a tubular battery, make sure you understand your needs perfectly and are aware of the environment you are residing in. For places that have hot and humid weather conditions, like Chennai, all of the above Nantech Tubular batteries work perfectly well.

Introuction:

SMF (Sealed Maintenance Free) batteries, also referred to as the Value Regulated Lead Acid (VRLA) batteries are flat plate batteries that do not require topping-up and normally do not emit any fumes or gases on a never-ending basis. They eliminate the risk of acid spillage during transportation. Due to their construction it can be mounted in any orientation and does not require constant maintenance. These are utilized for high-end applications of standby power like UPS, Electric Converter, Railway Communications, and Security Systems, etc.

Power cuts and load shedding can be quite troubling. And getting an inverter-battery setup helps a lot. But choosing an inverter battery might be a daunting task for most of us, especially if you are getting it for the first time. Don’t worry, we at Nantech decided to put this comprehensive guide and here’s everything you need to know before getting one:

How Long Do You Need A Power Backup?

Knowing how long you need the power backup to last, helps you choose the battery with the right capacity. Let’s say you face power cuts for 2 hours everyday and you need a 12V battery as a power backup for the entire time. And you want to run the following appliances:

Required Capacity of Battery = (Hours of Power Backup) * (Power Required in Watts) / (Voltage of Battery)

Required Capacity of Battery = 2 * 270 / 12 = 45 Ah

Most batteries in the market are around 135-150 Ah and if the above case is equivalent to your real requirement, then you can even go for cheaper and lower capacity batteries!

Cost
It is essential to calculate and decide the budget as per your requirements, since the inverter and battery dealers may persuade you to buy more expensive batteries. The above example will help you with the necessary calculations and prevent unnecessary expenses.

Battery Type
Lead Acid Battery:
These are of two types:

• Flat plate battery: recommended for areas with frequent power cuts, lasting short durations.
• Tubular battery: it’s bigger than flat plate battery and is recommended for areas with power cuts lasting long durations but fewer in frequency.

Gel Battery:

• Recommended for offices and homes where power backup lasting several hours is necessary.
• Zero reduction in performance, even after years of usage.
• No water top-up and maintenance required.
• Easy installation.
• Eco-friendly battery with minimal toxic emissions.
• No chance of acid spillage!

Weight of the Battery

The weight of the battery is something you might overlook and not take into consideration first but it tends to be an important factor for those who are frequently on the move! Batteries have different weights when they are filled and empty(dry). If you frequently shift places, consider buying a less bulky battery. In case you still need a heavy battery, look for the ones equipped with a trolley.

Replacement, Warranty and Services

Most reputed companies offer free services within the warranty period (also called ‘flat warranty period’). In case your battery faces issues within a few months of purchase, it could be replaced, provided the fault occurs and is registered within the replacement/pro-rata warranty period. It also helps if the company provides installation and maintenance services, since this can be a tough task for most individuals. Hence, warranty period is also an important factor while purchasing a battery!

We hope this comprehensive guide helped you and made the task of buying a battery easier! If you are looking for an authorised battery dealer, we at Nantech sell batteries of numerous reputed companies.

SAFETY FIRST

Electrical systems form a crucial part of every organization that runs on electrical devices. If there is even a little problem in the system, it shuts down, and the movement of work in the organization comes to a standstill. This is where power quality audits come into the picture. They act like bulletproof jackets for the electrical system. It checks the safety and efficiency of an organization's electrical system.

How does PQA work?

It works in the following ways :

• Checks the quality of voltage- it maintains the network's frequency, thereby ensuring that there are no high or low-frequency disturbances present in the network that may be capable of damaging components of the system.
• Checks the continuity of power supply - it ensures that the power is constantly available in the network. All the connected devices are operating consistently without any hurdles, and that the efficiency of not a single appliance has been compromised.

Importance of PQA :

• Provides a wholesome picture of the electrical system's state and its operational statistics at any point in time.
• Analyzes variations in voltage, flickers, frequency variations, harmonics, etc.
• Ensures the devices' good performance connected to the electrical system by providing enough voltage and deterring any fluctuations.
• Develops schedules for maintenance of the power system.
• Assessment of the sensitivity of all equipments and disturbances of any data caused to the equipment, can be prevented well in time.
• Identify the source of the event and the frequency of events.
• Helps by monitoring the conditions of the electrical system.
• Helps in the evaluation of performances against various specifications.
• Assists in predictive maintenance.
• It identifies the exact location so that the specific source is recognized and the problem is resolved.
• Identify the precise timing of events.
• Gives a precise report that helps in preventive maintenance to know all the measures that need to be taken promptly in case of disturbances.
• It improves the power quality and brings in efficacy.

Consequences of bad power quality can inflict serious losses to your company in case there is a disruption in the flow of a sinusoidal wave of power supply, which could cause significant damage to your electrical system, in turn affecting the supply to your devices. By this, not only are your devices getting damaged, but there is also a breach in the working momentum among your employees. This will further reflect the progress of your firm. A power quality audit can enable you to maintain good power quality and, in this way, discourage any hindrance that comes in the way of your company's prosperity.

To summarise, one can say that a power quality audit determines how fit your electrical system is. Moreover, it acts as a warning system and helps stave off any electrical issues, thereby protecting your power system and the appliances connected to it. Nantech Power Systems Pvt Ltd is one such company based in Chennai that provides you with top-notch Power quality audits.

It is annoying when essential data is lost simply because of an unexpected power cut. The frustration and not to mention the potential loss of work and efforts can spoil anybody’s mood. Power cuts hamper not only digital data but may as well damage factory goods if the energy supply stopped abruptly. Thankfully, the invention of inverters helped us restart our power and avoid grim situations, but another device went another step further! The UPS that stands for Uninterrupted Power Supply, trumps the inverter by its ability to back up the power supply so rapidly that there was virtually no interruption.

The UPS is an essential device, that also serves to protect other devices from the adverse effects of power fluctuation and power cuts. It is essentially a back-up current supply in the instance of the failure of the primary power source. It is not used for heavy factory equipment and is primarily used for computers. Unless, your locality, office, or residence faces frequent power cuts, we at Nantech recommend that you rent a UPS and not buy one. Since Chennai has a booming IT industry, and many more investments in the IT sector are predicted to come their way, Chennaites should consider investing in renting a UPS.

There are some indications for renting a UPS:

Budget: If you are short on budget, renting a UPS will cut down on installation fees!

Nomadic work environment:
If you travel frequently for work or otherwise and do not want to test the power system at a new location, it is advisable to rent a UPS instead of carrying the bulky device everywhere you go.

Things to be kept in mind while renting a UPS are as follows:

Rental Clause:-
Always read the rental agreement provided by the UPS provider carefully. Consider factors like monthly rent and service policies and run a cost-benefit analysis before making a decision. Rental duration should be given a lot of thought as it will also it will also impact the number of service appointments.

Battery status:- You should receive a new battery with every UPS rental. Make sure the battery works and get it installed by a professional.

Type of UPS needed:
Depending on use, choose any of the three most common systems.

• Stand-by UPS:-

It is best for home use, supplying light equipment like computers and such.

• Offline UPS: -

It is best for shops and intermediate level commercial use.

• Online UPS: -

This is the most efficient and advanced model, suitable for industry and factory-grade equipment.

Maintenance:
Rent a UPS that will require less maintenance. The provider in standard practice, along with the UPS also provides maintenance services which can be scheduled at the convenience of the consumer. Servicing charges are nominal unless new parts need to be added or replaced.

Safety and Technical Compliance:
Any device when purchased or rented should meet standard safety guidelines, and the UPS system, irrespective of type, is not exempted from this rule. Remember to read the instruction manual, and understand that it is your right to ask for a copy of the warranty certificate of the device. Try to rent a user-friendly system that will not take much skill or knowledge to attach to other equipment.
