Description
GMS-IV is a low-noise measuring preamplifier for monitoring gas insulated switchgear (GIS). This amplifier technology allows to detect the broadband transmissions small defects or impurities in the GIS. Thus, vulnerabilities can be detected early and damage can be avoided. The amplifiers are powered via the coaxial cable at the output. A protective circuit at the input prevents the destruction by excessive input power.
Trusted by manufacturers and commissioning organisations around the world.
