Wega T1 | Wega T1 vario
Voltage display system for insulated medium-voltage transformers
The Wega T1 is a 3-phase voltage display system for touch-safe insulated medium-voltage transformers. The Wega T1 can be used in the surface-mounted housing in new and existing transformer stations. Its use is recommended in conventional medium-voltage transformers, but especially in remotely installed medium-voltage transformers or if there is more than one transformer in a station/building room. The display test function allows the display to be checked in the installed and de-energized state. An LRM interface or a measuring point for phase comparison is not provided due to the weak capacitive decoupling caused by the application.
The Wega T1 vario offers the same functionalities as the Wega T1. For maximum adaptability, there is an adjustable capacitor block on the back of the device. This makes it possible to choose between different adjustment capacitors.
The following medium voltage states are displayed:
 |
Tension present |
Switch-on threshold of the voltage display: 0.1 – 0.45 x Un. |
 |
Voltage present and integrated Repetition test passed | The current flowing through the indicator fulfills the requirements for current monitoring according to VDE 0682 part 415 (IEC 61243-5), section 5.28 (repetition test on integrated VDS). Continuous monitoring means that a periodic test is not necessary. |
 |
Voltage present and integrated Repetition test passed, but voltage signal too high | Installation note: Voltage signal too high. This is usually caused by an undersized balancing capacitor, an earth fault or operation of the switchgear at a higher rated voltage than originally intended. |
 |
No voltage present | When all poles of the system are switched off, all symbols are switched off. Voltage present <0.1 x Un. |
The built-in display test function on the front allows the display to be tested when installed and de-energized. Shielded or unshielded cables with compact plugs (AMP) can be connected to the fault direction indicator.
