1.Introduction:
FPWH type active energy transmitter, FPKH type reactive energy transmitter is an instrument for measuring active and reactive energy, FPWWH type active power / active energy, FPKKH type reactive power / reactive power combined transmitter It is a dual-function instrument that can measure both active (or reactive) power and active (or reactive) power. It is an auxiliary instrument for energy metering, energy-saving automation and computer electricity billing.
FP series electric energy transmitter technical indicators fully comply with the requirements of JJG 596-89 "Electronic energy meter", the relative error is less than 0.5%, and has excellent temperature characteristics and long-term stability, coupled with electric energy display recording device, can be used In the grid dispatching system, it is also an ideal solid-state electric energy meter.
The transmitter is suitable for single-phase, three-phase (balanced load and unbalanced load) lines with frequency of 50Hz, 60Hz and special frequency. The electric energy is pulsed output with two types of optocoupler open collector or relay contact to adapt to different RTU and power recording device. The digital output corresponds to the active (or reactive) energy measured by the input. The output lead is four wires, and the bidirectional digital output outputs electrical energy in both positive and negative directions.
