Description

AOB**2E/9&#***3;5multifunctional network electrical instrument (instrument for short below) is the electronic measuring instrument developed for measuring the all parameters of the electric network. The measured parameters display on the five displays. It can measure and manage more than *0 electrical parameters at the same time and input network, current and voltage ratio can programmable. It supplies maximum and minimum of phase voltage(three-phase four-wire), line voltage(three -phase three-wire), phase current and total current; while it also supplies demand value of phase current, total current, total active power, total reactive power and total apparent power. The instrument is provided with four switching value input channels, two energy pulse output channels, Rs**5 communication output and can add four switching value output channels or four analog transmitting output channels. It can instead the common electrical transmitter, measuring indicating instrument, energy indicating instrument and other relative accessory unit instruments.
