Problems

• Insufficient accuracy of conventional current and voltage transformers

Traditional current transformer

→ system accidents

→imbalance of power

→ losses 100 million RUB in month

• Incorrect operation of relay

protection

• Problems with high voltage insulation. Potential of explosion and fire

• Analog CT and VT don’t correspond to the innovative concept «Smart GRID»

03

Product

Structure scheme of DCVT with

optoelectronic interface

Advantages• Service is less, saving of 10% of transformer cost

• High measurement accuracy (4 times higher)

• No distortion of the current

• Using digital electrical substations SMART Grid

Composition•Current and voltage sensors on 5 physical principles

•Digitization on the primary side (on the high voltage)

•Solid insulation

•Fiber optic (radio) transmission
