Cambridge Sensotec has released the SF6 Multimeter with internal pump for low-pressure SF6 testing.
The Rapidox SF6 Multimeter with the internal pump allows the condition testing of Gas Insulated HV electrical assets at gauge pressures down to zero.
It measures percentage SF6 and also detects the presence of the impurities SO2 and moisture.
These measurements provide full condition testing of insulating gas and give an indication of whether partial discharge has occurred in the SF6 insulated switchgear.
