Note: Model EPCZ-27/54/108-108, EPCZ is the model of series, 27/54/108 is: voltage of one reactor (kV)/voltage of two reactors in series connection/voltage of four reactors in series connection. 108 is the total capacity (kVA).The test object is the common configuration for reference only. For details, please contact with us.If the capacity of your equipment is small and voltage is too low, can add more reactors to increase the capacity, and add more divider to increase the test voltage.
