BL-M

Voltmeter

Product Features

  • 2-pole resistive voltmeter
  • Designed for direct measurement of alternating voltages in medium voltage distribution networks of 10 – 24 kV / 50 Hz
  • Accuracy >99 %
  • Application on MV switchgears, transformers

The two-pole resistive BL-M type voltmeter is designed to precisely and directly measure phase-to-earth voltages in three-phase medium voltage distribution 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 to 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.
