The Basics of VLF Testing | HV TECHNOLOGIES, Inc. low frequency (VLF) withstand testing is the application of an AC sinusoidal waveform, generally at 0.01 – 0.1 Hz, to assess the quality of electrical insulation in high capacitive loads, such as cables. During the test cables are subjected to a test voltage significantly higher than what they experience during normal operating conditions.

Switchgear - Wikipedia switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
