Megger Insulation Resistance Test 2 – Typical Megger test instrument hook-up to measure insulation resistance. The generator can be hand-cranked or line-operated to develop a high DC voltage which causes a small current through and over surfaces of the insulation being tested (Fig. 2).This current (usually at an applied voltage of 500 volts or more) is measured by the ohmmeter, which has an indicating scale.

Switchgear - Wikipedia for lower voltages may be entirely enclosed within a building. For higher voltages (over about 66 kV), switchgear is typically mounted outdoors and insulated by air, although this requires a large amount of space. Gas-insulated switchgear saves space compared with air-insulated equipment, although the equipment cost is higher.
