Portable Variable Frequency Resonant Withstand Voltage Test Set , For MV Cable and Power Substation Test
I. Product Usage :
FKTF portable variable-frequency series resonance test device mainly aims at AC voltage test for electric equipment and electric systems below 110kv. The reactors and excitation transformers employs dry-type epoxy resin filling, small size and light weight convenient for field moving, series or parallel composition is available, which can meet the test requirements not only of transformer, GIS,breaker, mutual inductor and bushing but also that of cable below 110kv
