Impulse / Surge Tester

7700/7710/7720

7703/7713

The best solution for coils testing

Coils are used widely. They are used on transformer, motor, generator, relay, solenoid, filter and

different inductances. That is why the quality of coils is very important for all manufacturers.

High voltage non-destructive analysis of winding identifies difficult to detect

manufacturing faults

They are a number of parameters that can not change during manufactre that may affect the

performance of a winding. These paramenters, which cannot always be measured with an LCR

Meter, include change in material as well as shorted and damaged windings. The 7700 series

instruments use a very high voltage impulse to stimulate the device under test (DUT). It analyzes

the decay waveform to detect changes in material, shorted and damaged windings and other

errors. Long term decay of a winding can also be detected. The system used ensures that the

component is tested but not damaged during the analysis process. The shape of the waveform

is dictated by Q factor, Inductance and stray capacitance of the winding. Hing Q shows as

a slow decay and the frequency of the waveform is determined by the inductance and stray

capacitance of the DUT.
