Specifications and Product Details:

Three-phase Electronic Multi-function (Checking within transformer district) Watt-hour Meter DT (S) SD988

Introduction of products

DT (S) SD988-type three-phase electronic multi-function (checking within transformer district) watt-hour meter is a newly multi-function meter, with special application in low-voltage power spots to accomplish checking and management of power within the transformer district. The products have adopted advanced measurement chip and communication chip, featured with high integration, high precision, good stability, reasonable layout, advanced technology, great utilization, powerful function, friendly operation, etc.

Functions

Power Measurement function

Make time-measuring of positive and negative power (active and reactive), and four-quadrant reactive power.

Maximum power demand metering

Make time-measuring of the maximum positive and negative power (active and reactive) demand. And it has power demand resetting function.

Multi-rate function

It can program 4 rates, 10 day time consumption, 5 day time consumption table, 4 time zones and 12 public holidays.

Freeze function

Freeze and store automatically the power consumption at each hour of the custom day, at the end of time zone, on the custom day of automatic meter reading.

Load curve function

According to users’ settled time, it will execute curve record about the 6 selected groups of data in interval, and the shortest recording interval is up to one minute.

Events recording function

Record various events such as loss of voltage, loss of current, voltage passing rate, power-off or power-on state, programming, power demands clearing, broadcasting timing, etc.

Three-phase (without voltage) current detection

It can record the latest occurring time of current (without voltage), as well as its total degree and accumulated time.

Alarm function

Support the light-control alarm and voice-control alarm.

Swift tripping in the case of overload

The meter will output swift tripping signal when the load exceeds the settled load value.
