MID approved EM4373 CT 3*230/400V 0.05~5(6)A
three phase power quality analyzer electricity meter
The EM4373 three phase power quality analyzer is a standard four-module 72mm width, which can be used for single-phase two-wire/three-phase three-wire/three-phase four-wire power grids.The instrument provides real-time monitoring of A/B/C three phase Voltage(L-N,L-L), Amp, kW, kVA, kvar, PF, include maximum,minimum, average values. Phase angle, voltage phase sequence indications and Voltage asymmetry & current asymmetry. PT ratio& CT ratio selectable, THD up to 41th order for voltage& current and Maximum demand on Amp & kW& kVA.
The instrument is connected to an external miniature contactor, which can realize remote on/off control of household equipment; The meter can also be used in a dual-power system to measure grid and generator charges; The instrument's RS485 communication port allows remote system connection to provide all parameters in real time.
