Four components inside an innovative device:
Electronic Current Transformer
Electronic Voltage Transformer
Voltage-indicator lamp
Insulator
The sensor can be easily installed in medium voltage distribution switchboards (primary and secondary) for protection and measure functions as an alternative to traditional voltage and current transformers and insulators with capacitor divider.
The voltage transducer is based on an electrical fi eld sensor, galvanically isolated from the busbars, while the current transducer is based on a special Rogowski sensor.
