Features
It is possible to measure 3-phase voltage, phase-phase voltage, active power, reactive power, apparent
power, active electric energy, reactive electric energy, power-factor, frequency and so on and it is
reliable and easy to assemble. It copes with the power failure by storing the active electric energy and
reactive electric energy inside the ferroelectric RAM.
The measured parameters monitor various parameters of power line using 3-Segments display windows
and CT ratio and PT ratio can be set using the front panel to display 3-phase voltage, phase-phase
voltage, active power, reactive power, apparent power, active electric energy, reactive electric energy,
power-factor, frequency and peak power. It has an alarm function to display the alarm when the voltage
input value is set and it is input less than the set value.
