A compact system of universal multipolar power connections in the circuits of current transformers and voltage transformers of relay protection and measuring devices
For modern security systems, which are becoming more complex, basically three different types of checks are used.
1. Initial check at first commissioning of the device.
2. Pre-launch check.
3. Performance verification during operation.
POCON universal blocks equipped with a cover status contact are designed for connecting 4 and 8 circuits of a current transformer or voltage transformer. An innovative integrated system provides automatic short-circuiting of the current transformer windings before disconnecting it from the circuit.
