Watt hour meter for the customer of the contracted power less than 26.4kW of three-phase low voltage to detect voltage and current |
|
|
Induction-type watt hour meter, which the effective magnetic flux of voltage and current is induced to a disc to rotate according to the load phase angle so that it accumulates effective power to a measuring device according to the time elapsed |
|
 |
|
Good current properties by being designed to obtain the most effective magnetic flux with the lamination of the silicon steel sheets having good magnetic properties for the part of a drive device |
|
|
Minimized change of properties over a time elapse by reducing frictional torque of a bearing with the uses of the double structure for a 300% device and the magnet bearing for a 400% device in consideration of a bearing’s change of a rotor over a time elapse |
|
|
Design of good temperature properties against a wide range of change of ambient temperature by the 1st and 2nd temperature compensations |
|
|
Minimized frictional torque by making a gear and a pinion by resin for a gauging device |
