By means of the measurement values of
voltage and current BLR - CM calculates the
conditions in the network. As standard, the
voltage L1-N and current in L1 is used. The
separation of auxiliary voltage and voltage
measuring allows a voltage measuring range
between 50-530V. Additionally, there is the
possibility to change the phase-shift
between voltage and current in steps of 15
degrees. The result is the maximum possible
flexibility of the relay for applications
with voltage measuring phase/neutral,
phase/phase and for mixed measuring with
different transformer types.
The BLR-CM is measuring the temperature in
the panel by using the integrated
temperature sensor. This measurement value
can be handled flexible, eg; it can be used
for an alarm message. By the means of the
digital output an additional fan can be
activated
