HIGH VOLTAGE INSULATION BREAKDOWN TESTER
AC
|
dot - 4500 series
|
|
|
INTRODUCTION:
High Voltage Breakdown tester is useful for checking high voltage withstanding capacity of insulation
material. Therefore to determine the quality of insulation. The test level depends upon the working
voltage of insulation material / electrical apparatus or as per ISI requirements.
|
APPLICATIONS:
Useful for manufacturers of Insulation Material, Transformers, Switchgear, Varnishes, Pump, Motors,
Electrical apparatus, Cables, Wire, Capacitors, Electrical & Electronics component manufacturers.
