The Wega 1 R2 determines the absence of voltage in two-phase railway networks with autotransformer system (16.7 / 50 / 60 Hz).
Due to the display test function built into the front of the Wega 1 R2, it is possible to test the display in the installed and de-energised state.
Shielded or unshielded cables with flat plugs or system plugs can be connected as connecting cables.

Wega 1 R2 is a two-phase voltage testing system that indicates subsequent medium voltage conditions:

Indication	Definition
	Voltage present Threshold value for voltage presence indication: 0.17 – 0.78 x Un.
	Voltage present and passed maintenance test Integrated maintenance passed
	Voltage present and integrated maintenance test passed Voltage signal too high.
	Voltage not present
