Product Details

Purpose:

The DD862 model DD862a single-phase energy meter is an induction instrument used to measure single-phase AC active energy with a frequency of 50Hz. It mainly consists of electromagnetic components, rotating disks, bearings, damping magnets, meters, and adjustment devices. This meter has the characteristics of high precision, high sensitivity, and long service life.
The quality and technical indicators of this product comply with the national standard GB/T15283-1994 and the international standard IEC521-94.

Organizational characteristics:

The voltage iron core adopts a semi enclosed insertion type, and the current element adopts a two-stage compensation to enable the meter to measure a wide load characteristic. The fully plastic sealed voltage coil can withstand instantaneous high voltage surges. Double gemstone bearings or magnetic bearings ensure the service life of the electric energy meter. Double stage nickel cobalt damping magnetic steel has high coercivity and stable magnetic properties. The electrical performance complies with the IEC521 international standard.
