Wega 1 LV
Integrated voltage detecting systems in accordance with IEC 62271-213 for low-voltage applications
The Wega 1 LV is an integrated voltage display system. The device is used to determine and display the operating status of three-phase
low-voltage systems (without neutral conductor) in accordance with IEC 62271-213. The Wega 1 LV is based on the requirements for voltage detection and indication systems (VDIS) in accordance with IEC 62271-213, with the exception that IEC 62271-213 applies to rated voltages greater than 1 kV and that the Wega 1 LV has been designed accordingly for low voltage. The Wega 1 LV may only be operated as a complete system in combination with the interface box included in the set and the corresponding connection cable. The display test function built into the front of the device allows the display to be tested in the installed and de-energized state.
The following medium voltage states are displayed:
 |
Tension present | Switch-on threshold of the voltage display: approx. 50 V (deviating from the percentage thresholds of IEC 62271-213!) Installation note: When operating the system with nominal voltage, the voltage signal is too low. This is usually caused by incorrect use of the Wega 1 LV, e.g. operating the switchgear at a lower nominal voltage than originally intended. |
 |
Voltage present and integrated Repetition test passed | The current flowing through the indicator fulfills the requirements for current monitoring in accordance with IEC 61243-5 (section 5.28) and IEC 62271-213 (section 11.4.2). Continuous monitoring means that a periodic test is not necessary. |
 |
No voltage present | When all poles of the system are switched off, all symbols are switched off. Voltage present <50V (deviating from the percentage thresholds of IEC 62771-213!). |
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.
