SEPS Series Energy Storage High Power Test System is an independent high power test system without large power from the grid network. With the 400V power supply and no more than 300kVA power, the system can operate the short circuit test (dynamic & thermal stability test) upon those power transformer, the distribution transformer, series reactor, instrument transformer and cable. It can also do the interrupting test, short-time withstand current test, overload test, and endurance test upon MV & LV switchgear and CBs.

SEPS series uses unique high-density energy storing units. These units and the inverters are all from the international top brand company with good quality. One 20’container can generate max 65MVA power, while one 40’ container can generate max 300MVA power, which also can be connected in parallel in max 4 units. From DC to AC, the system adopts the structure of power unit in series, and the inverting is through the PWM technology. It can adjust the voltage and frequency in a wide range and also make the adjustment for the phase angle and DC component. Close loop control avoid influence from output impedance.
