VMRC-10/3 is three phase Line voltage monitor (LVM) used to protect device
from Single Phasing, voltage unbalance, phase reversal and under/over
voltage. It shows real time voltages between phase and neutral.
There is an Output of alaram relay is given to the controller as SPPR input.
Features are easily understood by examples in the instruction below.
