WHO ARE WE?

K.S. Instruments LLP, popularly known as KSI, was established in 1973. KSI has been widely known as a leading designer and manufacturer of Power resistors and allied products.

In 2014, the resistor business was separated as KWK Resistors India Pvt Ltd to better manage the fast-growing business with the focus that it needs. KSI continued to manufacture Electrical Junction boxes for Power generation industry. Towards end of 2016, KSI developed and tested a wide range of Low Tension Instrument Transformers. KSI invites you to explore the various product ranges through the Product section of the site. KSI assure to continue providing world class components and aiming to surpass your expectations everytime.

OUR PRODUCTS

LOW TENSION INSTRUMENT TRANSFORMERS

KSI range of Instrument transformers are electrical devices used to isolate or simply transform voltage or current levels to measurable levels. Typical applications of instrument transformers include Metering - high voltage or high current circuits and Safety - isolating secondary control circuitry from the high voltages or currents.

With the use of Instrument Transformers, the large voltage and current of an AC Power system can be measured by using small rating measuring instrument i.e. 5 A, 110 – 120 V. Also measuring instruments can be standardized. Which results in reduction of cost of measuring instruments.

KSI provides solutions for two types of Instrument Transformers
