AIS - Air insulated substations - EEP· For these reasons, the use of transmission voltages as high as 765 kV has occurred. Transmission system substations that provide bulk power operate at voltages from 69 to 765 kV. Common voltage classes used in the United States for major substations include 69, 115, 138, 161, and 230 kV (considered high voltage or HV class) and 345,500, and 765 ...

Gas density monitor - GDM-063 - WIKA Singapore density is a crucial operating parameter for high-voltage switchgears. If the required gas density is not present, safe operation of the plant cannot be guaranteed. The WIKA gas density measuring instruments provide reliable warnings against dangerously low gas concentrations even in extreme environmental conditions.
