HV Diode Tester

Diodes are essential components of electrical machines and should be tested routinely to identify early signs of fatigue or deterioration. The HV diode tester has been designed by our in-house testing experts and is used to determine the condition of HV Diodes and Thyristors as used on power generation rotating diode assemblies.
