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.

PD -
Shanghai Jiuzhi Electric Co., Ltd.
Partial discharges (PD), as defined by IEC60270, are localized dielectric discharges in a partial area of a solid or liquid electrical dielectric insulation system under high-voltage field stress. It can be caused by discontinuities or imperfections in the insulation system. PD testing thus gives an indication of deterioration of the insulation and is an indicator of incipient faults. In general PD will occur in systems operating at voltages of 3000 V and above; it should be noted though that in some cases PD can also occur at lower voltages.

HCTS Series -
Shanghai Jiuzhi Electric Co., Ltd.
The HCTS Series Cable Heat Cycle Test System is designed to raise and control the temperature of conductor or other low impedance electrical loop to simulate the current loading conditions found in the electrical circuits up to 10000A.
-
CTTS Series -
Shanghai Jiuzhi Electric Co., Ltd.
CTT series cable test terminations are used to test Plastic insulated high-voltage cables. The specific advantages of this series versus conventional terminations are fast and convenient assembly. The terminations can be used for partial discharge (PD) measurements, impulse voltage testing, loss factor (tan delta) measurements and, if the cable ends are carefully prepared, for breakdown testing (step test).

YDTW\YDTCW series -
Shanghai Jiuzhi Electric Co., Ltd.
Conventional AC test transformers are especially designed for testing objects of medium capacitance. These systems are particularly suited for tests requiring stable voltage even if the load changes under voltage (corona, wet & pollution tests) or when the load is inductive (inductive voltage transformers). The possibility of stacking several of these transformer modules allows reaching very high voltage levels by keeping reasonable floor space.
