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.
