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
