| Application︰ | Type SY1050 serial three phase watt-hour meter is a kind of new style three phase electronic watt-hour meter, it is used for measuring active or reactive energy power loss in frequency 50Hz or 60Hz three phase AC electricity net. The active meter completely accord with relevant technical requirements of National standard GB/T17215-2002 and International Standard IEC61036. The reactive meter completely accord with relevant technical requirements of National standard GB/T17882-1999 and International Standard IEC61268. |
| Functions and Features︰ | 1. Accurate metering of 3-phase active electric power. Its circuit design and components are selected for operating in bigger environmental difference, therefore long time stable operation of the complete machine is ensured.
2. Photoelectric impulse interface fixed at the stern facilitates error testing.
3. The Watt-hour Meter will work normally in absence of one phase for 3-phase 3-wire meter or 2 phases for 3-phase 4-wire meter.
|
| Structure and Features:︰ | 1. May select 5+1 digits register by step type or 6 digits LED or 7 digits LCD display.
2. The direction of electric power can be distinguished automatically, can measure unidirectional energy power, and has function of anti-stealing electricity.
3. Has indication function when power cut down and impulse output when no power.
