Instrument transformers are high accuracy class electrical devices used to isolate ortransform voltage or current levels. The most common usage of instrumenttransformers is to operate instruments or metering from high voltage or high currentcircuits, safely isolating secondary control circuitry from the high voltages or currents.
Transmart manufactures Cores for both low voltage and medium voltage current transformers and potential transformers, related products including Toroidal core, C core, Split core, Unicore core, rectangular core. Our Nanocrystalline cores are getting more and more popular for high accuracy class upto 0.2S Current Transformers.
