Description
This amplifier technology allows to detect the broadband transmissions of small defects or impurities in the GIS. Thus, vulnerabilities can be detected early and damage can be avoided. The LPB is connected to the GIS system between the sensor and the LAG and prevents the destruction of the GMS-IV amplifier by excessive input power.
