| Extra high voltage, low
corona, grounding relays of the air insulated type. Peak test
ratings up to 300KV and 100 amps continuous. Units can be
operated either by solenoid, motor, or air cylinder, with spring or
gravity return. All models have spherical contacts. When
voltage transient limiting is required, some models have an
adjustable sphere gap. Also available are units with built-in
high voltage discharge resistors with energy dissipation
capabilities from 50 to 10,000 ohms. Some units can be reduced
in height if full line to ground voltage is connected to the top
high voltage contact only and the other high voltage terminal is
operating at, or near, ground potential. Line to ground
voltage can also be increased by adding insulation between lower
high voltage contact and ground. Normally mounted base down.
Base up mounting if specified. |
