1 Two types of high megohm resistors are widely used: carbon-film and metal-oxide.

2 Pump before use, application megohm table to check the electrical insulation resistance.

3 Resistors with values of 1G. or more are often referred to as high megohm resistors.

4 Megohm inspection method is to form an electric cable terminal at the online access, another access terminal on the motor casing, megohm shake table to observe the value of insulation resistance.

5 The principle of wave process on the Line is used to measure the distance of power cable's high megohm fault. Its technical cruxes are presented in this paper.

6 The insulation resistance of these motors should be kept above 1 megohm.

7 The principle of wave process on the Line is used to measure the distance of power cable's high megohm fault.

8 On raining days, the insulation resistance of the generator often drops below 0.5 megohm.

9 And shake the electrical insulation resistance measurement and its value is not lower than 50 megohm.

10 Megohm inspection method is to form a terminal connected to the electric cable line, another terminal connected to the motor casing, the shake table megohm observed value of insulation resistance.
