Power meters are electronic meters intended for measuring active or reactive power in single phase or three-phase networks, with balanced or unbalanced load.
Power factor meters are intended for measurement of power factorb (cosϕ) in a three-phase three-wire network with a balanced load of phases or in a single phase network.
Meters with a moving coil and a rectifier are intended for measurement of AC currents or voltages in the frequency range from 40 Hz to 65 Hz (higher frequency range on request), where low meter ...
Meters with a moving iron are intended for measurement of AC currents or voltages of frequencies from 15 Hz to 100 Hz. They measure rms values independently on the signal form of current or ...
Bimetal maximum current meters with a bimetal measuring system are intended for testing the thermal load of transformers, cables, electrical machines, etc.
Combined bimetal maximum current meters are provided with a built-in bimetal system and a system with a moving iron. The meters are intended for testing momentary and thermal load of transformers, ...
