Voltage presence detecting and indicating systems and voltage detectors

The Wega 1 and Wega 2 series are three-phase voltage detection systems, which indicate several states of the operating voltage, and which, having an LRM front interface, are fully compatible with the IEC 62271-213:2021 standard. The fully encapsulated electronics of these systems increase their operational reliability and, due to their extended operating temperature range from -40°C to +75°C, they are suitable for a wider variety of applications. Thanks to the new design of the Wega 1 and Wega 2 series, with tool-free assembly and disassembly possibilities, considerable time is saved.

For increased flexibility, Wega 1 V and Wega 2 V allow capacity adjustment in a wide range of values.

Wega 2 and Wega 2 V allow remote monitoring of the voltage status through the auxiliary contacts they are equipped with.

Wega 1 R and Wega 2 R are single-phase or two-phase voltage detecting systems, which indicate several operating voltage states. These systems determine the absence of voltage in railway networks. The built-in display test function at the front enables verification of the display of the installed and de-energized unit.

Wega R series contains the variants Wega 1 R1 and Wega 2 R1 for voltage detection in single-phase railway networks and the variants Wega 1 R2 and Wega 2 R2 that detects the presence of voltage in two-phase railway networks.

In addition to the LCD display, the Wega 2 R has 2 LEDs (green U=0 and red U≠0) as well as 2 auxiliary contacts through which the voltage status can be monitored remotely.

The Wega T1 is a 3-phase voltage detector for insulated medium voltage transformers safe for touching. It is installed in a surface mount housing for applications in new and existing transformer stations. The built-in display test function at the front enables verification of the display of the installed and de-energized unit. The test points are not suitable for an LRM phase comparator due to the weak capacitive coupling which is associated with the specific application of the devices.

The integrated USB interface is used to retrieve the stored data results for further evaluation. Besides the information on the next maintenance test and the indication of the battery status, the Orion M1 device provides the option of setting the frequency.
