■■ Application on MV switchgears, transformers
Te c h n i c a l D a t a
The two-pole resistive BL-M type voltmeter is designed to precisely and directly measure phase-to-earth voltages in three-phase medium voltage networks of 10 – 24 kV/50 Hz. Measured voltages are digitally displayed up
to >99.99 per cent. Thanks to its accurate measurement feature, the BL-M device can also be used for voltage
calibration.
The device is designed and built in accordance with DIN EN 61243-2. It is intended for the use on switchgears,
transformers and other medium voltage applications. This device must not be used as voltage detector according
to DIN VDE 0105!
The structural design is based on the proven BL series voltage detectors which have been providing many years
of reliable service. As with the predecessor model, the BL-M device offers the user easy and advantageous handling, dismounting and transportation capabilities.
