Insulation Resistance Rules at Alejandro Brown blog

Insulation Resistance Rules. Insulation resistance tests are commonly measured directly in megohms or may be calculated from measurements of applied. As a general rule of thumb, insulation resistance should be approximately one megohm for each 1,000 volts of operating voltage, with a minimum value of one. After the required connections are made, you apply the test voltage for a period of one min. For example, a motor rated at 2,400 volts. This is the simplest of the tests. An insulation tester or megohmmeter can be used to determine the insulation resistance of a cable, installation, motor, or appliance. One of the most fundamental of electrical installation and maintenance tasks is taking insulation resistance (jr) readings. This is done to verify the integrity of the insulating material, be it wire and cable insulation or motor/generator winding insulation. The dc measuring voltage and the magnitude of the insulation resistance must comply with the requirements in table 2. Insulation resistance should be approximately one megohm for each 1,000 volts of operating voltage, with a minimum value of one megohm. The principle is to apply a known dc voltage.
