タイトルまたは説明

WS**0, a multi-functional poly phase static electricity meter. It is developed under the ongoing technology evolution in the commercial & industrial sector and in order to meet the growing customer demand for static meters.
It gives advantages to all users in the process: an installer, a maintenance engineer, a service engineer, a readout operator and a final user. The meter is approved and manufactured in compliance with the IEC *******1, IEC *******1 (IEC ****6) standards, and was designed according to even higher internal PAX standards.

Reliability and stability
With proven electronic technology, long-life components and special care in the manufacturing process, WS**0 guarantees precise accuracy and high reliability throughout its life span.  Re-calibration is no longer necessary.

Fast and Easy Installation procedure
This design is easy to handle and extremely efficient for large-scale residential installations. Adapted to current connection standards the meter is compatible with existing installations and test benches.

Local metering data display (LCD):
    * Automatic Scroll mode
    * Manual scroll (by )
    * Test mode (for utilities)
Programmable data set and sequence
LCD back-light: optional
LCD display when power absent: optional

Flexible Tariff Management
Benefit from an internal RTC, full Time of Use (TOU) function is realized.

A tariff program is managed by the RTC which is suitable for the most complex metering applications.

The meter is able to generate “End of Period” information as defined by the user, usually based around billing dates.

The non-volatile memory is able to save energy information for up to *2 billing periods. This removes the need to visit the meter on a frequent basis.

WS**0 supports 4 kinds of tariffs and *2 intervals in *4 hours for each day, which can be programmed flexibly. Interval 1 to *2 of each day can be combined with tariff 1 to 4 according to various requirements, this combination is called Tariff Set.

In addition, the meter supports  holidays & weekends, which can be individually set with different kinds of combination of tariffs and intervals.

Maximum Demand
Maximum Demand information can also be measured for all tariff rates allowing optimum billing of high consumption customers in particular.

  total and export energy
-Optional abnormalities alarms &logs
-Independent sealing of the meter body and terminal cover
-Not programmable via keyboard

Load Profile

The meter has 2 load profile channels which can store optional data for up to 2M capacity. And the interval length can be set from 1 to *0 minutes.

Instantaneous Value

WS**0 Measures all kinds of parameters:
kW sum of phases and per phase
kvar sum of phases and per phase
kVA sum of phases and per phase
Frequency per phase
Power factor
Current per phase
Voltage per phase

Freezing Function

The meter has optional function to freeze appointed variable parameters at the appointed time. Operators can read out these parameters to analyze.

Self-diagnostic

Meter parameters  need to be set for the first time usage when out of factory. Instead,  LCD will have an indication if the parameters are not integrated
Meter will check the hardware operating well every time when power on again, and will alarm for accidental faults.

Full functional PC software

Running under branded Windows environment
Full reading and setting function via optical port or Rs**5 port.
Three security levels for operators:
   - administrator
   - setting & reading
   - reading only
Printed the programmed parameters selected by user
