Kahn Easidew Transmitter

Wethersfield, CT, USA — The U.S. Environmental Protection Agency (EPA) has designated SF6 as a greenhouse gas and has imposed regulations to limit the amount of SF6 that is released into the atmosphere. This presents a problem for power companies that vent SF6 during moisture measurement tests.

Most electric utilities and independent power producers use Sulfur Hexafluoride (SF6) as an arc quenching and insulating gas in high voltage circuit breakers and switchgear installed in their electrical transmission and distribution systems.

A forward-thinking US electric utility developed a method to measure the moisture content of SF6 circuit breakers without venting the gas to atmosphere.

This power company permanently installed Kahn Easidew 2-Wire Transmitters into single-phase and 3-phase SF6 circuit breakers to provide an on-line measurement of moisture content.
