The N27P is a programmable digital device used to measure the parameters of single-phase electrical networks. The meter measures and calculates the following values:
phase voltage
10 minutes’ mean voltage
current
active power
reactive power
apparent power
active power factor
ratio of reactive/active power
mean active power
phase shift
input of active energy
output of active energy
input of reactive energy
output of reactive energy
apparent energy
frequency
10 seconds’ mean frequency
time
maximum and minimum values of:
– phase-to-neutral voltage;
– current;
– active power;
– reactive power;
– apparent power;
– active power factor;
– tangent φ;
– frequency;
– average active power;
It is possible to enter transformer ratio of used external current or voltage transformers which will be accounted for in the measurement and calculation of all values. All values and configuration
parameters are accessible through the RS485 and USB interfaces.The meter output signals are galvanically isolated from the input and power supply signals.
