The GPWWH are electronic transducers converting active power and energy in single or three phase balanced or unbalanced systems
to simultaneously produce an analogue DC output for instantaneous power signal and a digital pulse
output for cumulative energy signal.
The GPKKH are electronic transducers converting reactive power and energy in three phase balanced or unbalanced systems to
simultaneously produce an analogue DC output for instantaneous power signal and a digital pulse output for cumulative
energy signal.
