1.  General description

The 

ekor

.rtk unit is electronic equipment developed to 

indicate the absence of voltage on medium-voltage (MV) 

lines. It is for use in local or remote control installations 

where information on the status of the lines is required.

The unit is built into the switchgear and uses the same 

capacitive current signal as the 

ekor

.vpis voltage 

presence indicators to perform detection functions. Thus, 

conventional medium-voltage line coupling systems such 

as voltage transformers are not required, as it takes this 

signal directly from the capacitor dividers installed in the 

bushings.

The 

ekor

.rtk unit is supplied duly installed, configured 

and factory-tested, fitted in the circuit-breaker and feeder 

functions of 

cgmcosmos

 and 

cgm

.3 system cubicles.
