Power quality analyser / fault recorder
KoCoS Messtechnik AG | Power quality analyser / fault recorder
Measurement category CAT IV
CAT IV includes circuits which are connected directly to the source of power for a given building.
There are very high levels of available energy (e.g. limited only by the power transformer) and arc flash can occur.
