24KV & 30KV
Surge Comparison Tester with
DC Hi-Pot Test
The 7024KHP and 7030KHP use the latest advanced power pack unit specially designed to test the windings of very large motors & generators. The lower impedance and increased capacitance of large windings requires higher instantaneous test voltage & test current. The power pack unit enhances the capability by providing a low source impedance surge generating circuit and high instantaneous currents to fully test the windings of large motors or form wound coils. As with a new enhanced feature of PC interface it can easily store the Surge test waveforms that can be printed when required.
