The HR-2 voltage detector is a "non-integrated high impedance" (VDS) type and is in full accordance with the IEC 61243 (part 5) standards.
Designed to be coupled with an insulator with a capacitive divider, the HR-2 has an internal capacitive impedance situated between 36 and 43.2 M and reactive at a voltage level of 70 to 90 V and a current of 2,5 µA at 50 Hz.
On the front side of the HR-2 detector, a test point has been integrated which allows for verification of the phase concordance with the detector installed in the receptacle. The voltage detector HR-2 is:
in accordance with the protection class II of the IEC 60536 standard, and can be tested in a conventional 230V - 19 mm plug.
on the connection side, all the contacts are protected by a 0.15µm "gold coating".
With a history dating back over 38 years, Mevoco nv has specialised, in particular, in the design and the production of medium voltage switches from 10 to 36 kV.
