DESCRIPTION
DT58 series three-phase watt-hour meter. including DT58/DS58 three-phase four/three-wire watt-hour metres and DX58/DX59 three-phase four/three-wire var-hour meters, are induction typr three-phase logn-service life meters. designed with advanced techniques.
Equitalbe structure, magnetic circuit design and strict thechnical control guarantee D58 meters stable metering, reliable function and low service costs. Through strict selection and post-treatment of the materials of electromagetic element and the magnetic compensation, D58 are entitled with good lead characteristic and excellent staring perrformance. And the low mechanical load of register, hte homogeneity of magnetic bearing and steady friction fo moving element ensure stability of accuracy during the service life.
The Dt58 series have been designed and manufactured in comply with IEC521 OR BS5685
