These panel are an essential element to the inside of a test-room or of a shieleded cabinet for partial discharge test.
They let to control and monitor constantly tension and the current of feeding and
disbursed, optimizating the power factor correction.
In specific case of partial discharge on the cables, such panel can be utilized to control some reactors able to correct the power factor caused by a capacitive load
determinated from the cable in test.
These panel can be realized also to pilot, with SCR systems, some transformers, for heating test of the cable, consenting also to record and to check constantly temperature reached by cable and the current ones that crosses it.
