A new type of sensor for the non-contact measurement of lightning and switching transient overvoltage in power system is designed.
- class="label">•
The design of the sensor is based on the capacitive coupling and Pockels effects.
- class="label">•
An experimental system in the laboratory is established to test the performance of the sensor.
