SGM Series -
Shanghai Jiuzhi Electric Co., Ltd.
Resonant Test Systems, type SGM is applied for the generation of a continuously variable alternating (AC) voltage of a fixed frequency (mainly 50 or 60 Hz) for high-voltage (HV) routine, type and development testing of capacitive test objects. They can also be applied for HV on-site tests, but SAMGOR offers for that application the more economic solution of frequency-tuned resonant test systems.

Shanghai Jiuzhi Electric Co., Ltd.
Nearly every high voltage equipment prior to delivery to the customer will undergo a test related to capacitance and tan delta for a final quality control. Such tests are in general made at a frequency for which the equipment is designed. The reasons for the tests are firstly that too high losses ( means high tan delta) may cause a breakdown, secondly, the manufacturer of a specific equipment knows the typical magnitudes which can be tolerated and which provide information about the quality of newly manufactured equipment, and these measurements can also serve for a comparison with later preventive measurements.
