PD Free AC Transformer Test Systems , PD Free HV Type Test Transformer Voltage Withstand System


I. Products Description and Application :


CQSB series PD free power frequency test transformer system is mainly used for power frequency voltage withstand for electrician products and insulation materials or insulation structure. It is also be used for PD free power frequency test power supply of testing objects such as transformer, mutual induction, arrester,etc. it is be used widely in electrician manufacturing department, power operation department, R&D institution and institution of higher learning.The voltage divider of the system has coupling terminal of PD signal , through equipped with 2 or 4 channels PD analyzer (optional), PD detecting for test object can be realized.


The model CQSB-500KVA/500KV has two stackable cylinder type Test Transformer in series connection to output 500KV test voltage and 1A test current. The duty cycle is 60mints on ,60mints off ,


Until now , this test set had formed many different serialized model according to different votage withstand test applications .The alike model can see other typical model at the following clause.
