Power network meter N13

Power network parameter meter N13 is designed to measure all basic parameters in 3-phase 3-wire or 3-phase 4-wire, balanced or unbalanced power networks, with the simultaneous display of measured quantities and the digital transmission of their values and their conversion into an analogue standard signal. It also enables the control and optimization of power engineering electronic devices. Voltages and currents are multiplied by given ratios of voltage and current measuring transformers. Power indication take into consideration the values of programmed ratios. N13 type meter also indicates in real time. The meter may be configured using buttons or our LPCon software(PD10 converter required).
 
N13 measures the following parameters:
rms a.c. voltage and a.c. current, neutral wire current, active, reactive and apparent power, active, reactive and apparent energy, different power factors, THD for phase voltages (available through RS485), THD for phase currents (available through RS485), frequency, average active power (e.g. 15 min).

The N13 Meter is used in control systems for monitoring of power network parameters
