Wega is a three-phase voltage testing system that indicates subsequent medium voltage conditions:
Threshold value for voltage presence indication: 0.1 – 0.45 x Un.
Installation note: The voltage signal is too low when operating the system at nominal voltage.
The cause is usually the selected adjustment capacitor which is too large or the operation of the
switchgear at a nominal voltage that is lower than originally envisaged.
|Voltage present and passed maintenance test|
The current flowing through the display unit meets the current monitoring requirements of
IEC 61243-5 and IEC 62271-213. A maintenance test is not necessary due to the continuous monitoring.
|Voltage present and integrated maintenance test passed; voltage signal, nonetheless, is too high|
Installation note: Voltage signal too high. The cause is usually the selected adjustment capacitor
which is too small, an earth fault or the operation of the switchgear at a nominal voltage that is
higher than originally envisaged.
|Voltage not present|
When the system is switched off at all poles, all symbols are switched off.
Voltage applied <0.1 x Un.
