Control and deflecting coil has a current limiting resistor connected in series so as to protect the external circuit in case of damages caused due to very low resistance. Testing voltage is produced by electromagnetic induction in case of hand-operated megger and by a battery in case of electronic type megger. The deflection of pointer increases with the increases in voltage in the external circuit and also decreases with the increase in current. That is, resultant torque is inversely related to current and directly related to voltage. While the electrical circuit that is being tested is open, the resultant torque caused due to voltage coil is maximum and the deflection pointer shows the value of infinity which means the circuit does not have any shorting present and resistance is the maximum within the circuit being tested. In the case of a short circuit, the deflection pointer shows zero which indicates no resistance in the circuit being tested.
A Megohmmeter or insulation resistance tester is a special type of ohmmeter used to measure the electrical resistance of insulators. Insulating components, for example cable jackets, must be tested for their insulation strength at the time of commissioning and as part of maintenance of high voltage electrical equipment and installations.
