Insulation resistance quality of an electrical system degrades with time, environment condition i.e. temperature, humidity, moisture & dust particles.

  • Insulation resistance quality of an electrical system degrades with time, environment condition i.e. temperature, humidity, moisture & dust particles.

  • It also get impacted negatively due to the presence of electrical & mechanical stress, so it’s become very necessary to check the IR (Insulation resistance) of equipment at a constant regular interval to avoid any measure fatal or electrical shock.









• Voltage for testing produced by hand operated megger by rotation of crank in case of hand operated type, a battery is used for electronic tester.

  • • Voltage for testing produced by hand operated megger by rotation of crank in case of hand operated type, a battery is used for electronic tester.

  • • 500 Volt DC is sufficient for performing test on equipment range up to 440 Volts.

  • • 1000V to 5000V is used for testing for high voltage electrical systems.

  • • Deflecting coil or current coil connected in series and allows flowing the electric current taken by the circuit being tested.

  • • The control coil also known as pressure coil is connected across the circuit.
