Capacitive voltage indicator (divider)
The transformer can be supplied with the capaci-
tive voltage indicator on the request. Integrated
voltage detection system is corresponding to Sep-
arable Voltage Detection System according to IEC
61234-5. It is integrated coupling electrode con-
nected to secondary terminal (terminal Ck). Elec-
trode acts as a capacitor between electrode and
primary winding (C1), or electrode and ground
(C2). If the electrode is connected to indication de-
vice (not part of delivery – it is part of switchgear)
it works as indication of voltage presence – more
in IEC 61234-5.
