To assess the insulating property of dielectric transformer oil, a sample of the transformer oil is taken and its break down voltage is measured. The lower the resulting breakdown voltage, the poorer the quality of the transformer oil.

• The transformer oil is filled in the vessel of the testing device. Two standard-compliant test electrodes with a typical clearance of 2.5 mm are surrounded by the dielectric oil.
• A test voltage is applied to the electrodes and is continuously increased up to the breakdown voltage.
• At a certain voltage level breakdown occurs in an electric arc, leading to a collapse of the test voltage.
• An instant after ignition of the arc, the test voltage is switched off automatically by the testing device.
• The transformer oil testing device measures and reports the root mean square value of the breakdown voltage.
• After the transformer oil test is completed, the insulation oil is stirred automatically and the test sequence is performed repeatedly: typically 5 repetitions, depending on the standard.
• As a result the breakdown voltage is calculated as mean value of the individual measurements.

NK Transformers is the leading power and home electrical specialist in India having a vast portfolio comprising of Power back up solutions such as UPS, Batteries and Solar Applications to Electrical offerings such as Fans, Wires, Switches and LED lighting.

We introduce our self as a seller of security cameras, video recorders DVR, NVR, surveillance systems. We supply security products to the government, businesses, and home owners alike of all shapes and sizes.

Details :

• All of our systems come fully equipped to handle all of your remote viewing needs. No matter where you are in the world, as long as you have an internet or 3G/4G connection, you'll be able to view your video feed at any time you want. Additionally, we provide our customers with a full list of readily available options for viewing; whether you prefer to use your computer, tablet, or Smartphone.
• Our technical support is unparalleled. It's one thing to say it but another thing to mean it. For as many years as we've been in the business, we have yet to come across anyone else who spends as much time with their customers as we do. You don't need to have an expert knowledge of CCTV systems, just a helpful and willing support staff that's more than happy to assist you with anything you may need.

At NK TRANSFORMERS, we perform electrical equipment testing on site, such as cables testing and transformer testing. We have a laboratory for electrical equipment testing. Here is a list of the electrical system testing we can perform. :

• Transformer testing
• High voltage transformer testing
• Current transformer testing
• Voltage transformer testing
• Protective relay testing
• Circuit Breakers
• High voltage circuit breakers
• Medium voltage circuit breakers
• Low voltage circuit breakers
• Regulators
• Station batteries
• Metering equipment
• Cable testing
• including cable analysis and cables underground
• Ground System
• Power quality testing
• Auxiliary equipment testing (arrestors, capacitor etc)

Few transformers fail due to old age or  as a consequence of external faults, short circuit faults, insulation failure (dielectric failure), local overheating (causing gassing) or accessory failure (e.g. bushings, tap changers, coolers, surge-arresters).

Repairing a transformer instead of replacing can substantially reduce investment costs and provide a faster turnaround than buying a new transformer. In repairing old transformers where the manufacturer may no longer be in existence and/or the design is obsolete and a like for like new replacement cannot be obtained, there may be significant savings in infrastructure costs and civil works in using the existing tank and design.

We provide solar home appliances for all your home needs from India's leading solar products firm. Why buy from unreliable and non-performing products that are labeled cheap when we provides with highest standard and the cheap label as well. We strives to deliver excellent and innovative solutions that can take care of your solar needs.

We have an internal liquid analysis laboratory for testing and analyzing equipment insulating liquid. Our quality screening program consists of testing for acidity, color dielectric strength, interfacial tension, visual, specific gravity and water content. We can also provide dissolved gas analysis for transformer insulating liquid.

Being the leading names in the industry we are involved in offering Installation & Commissioning. These are highly appreciated due to their flexibility and punctuality. Offered services are highly acknowledged among our clients due to their reliable nature. In addition to this, we offer these in a time bound manner.
