Instrument Transformers

SIEMENS offers most reliable, maintenance free Instrument Transformers with unmatched safety for Extra High Voltage in India ranging from 72.5 V to 800 kV, based on the technology of Trench – a world renowned Instrument Transformer manufacturer; now an integral part of Siemens globally.

The CT, EMVT and the Combi units are based on the state of art SF6 gas technology for Internal Insulation and Shatter proof Silicone composite Insulator for external insulation.

Some of the benefits offered by them are;
Explosion Proof design & No risk of fire – Unmatched safety
Completely maintenance free – Freedom from capacitance & tan delta measurements and routine cleaning of Insulators
Insulators with Hydrophobic properties – suitable for highly polluted atmosphere with lower Creepage distance requirement.
Superior Seismic Performance
Single Stage EMVT assuring better accuracy.

The range of instrument transformers offered by us cover
SF6 insulated Current Transformer (CT) with Silicone Composite Insulator
SF6 Electro-Magnetic Voltage Transformer (EMVT) with Silicone Composite Insulator
Combined Current and Potential Transformer (Combi Unit)
Capacitor Voltage Transformer (CVT)

Capacitor Voltage Transformer

The CVTs are of compact design with Oil Insulated Paper technology and porcelain insulator. The base tank and all metal flanges are made of leak-proof Aluminium alloy casting. The special Synthetic Oil used in Capacitor Stack enhances the electric stress handling capacity of the CVT enhancing the life of elements and reliability.
