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 19.99 kV. 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 IEC 61243-2. It is intended for the use on switchgears, transformers and other medium voltage applications. This device cannot be used as voltage detector according to EN 50110-1!
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.
A calibration and maintenance test is recommended on the basis of IEC 61243-2 in a cycle of 2 years.
