The new type proportional difference bi-channels electric field detectors can detects the development trends of vacuum level in vacuum interrupters
which makes the proportion between the voltage on the shield in vacuum interrupters and periodical high-frequency pulse voltage to be the monitoring parameter.The field testing shows that the detector can avoid the infection of periphery electric field effectively
has practical application value
and can be used for on-line monitoring of vacuum degree in vacuum interrupters.
