We offer “Power Sense” a Wireless Data Logger & that carries Power Quality Audit:

The advantage of our Power Sense products over most others is that these data loggers constantly sample information (recording the Min, Max and Average) over the set period. In contrast many other products only take 'snapshots' of what is going on and can miss 99.9% of the data that is critical to your overall analysis.

Some times the users are not aware of the seriousness of this LOSS FACTOR in their set up and users are paying as much as 30 to 40 % extra costs in their energy bills. We suggest POWER AUDIT to be carried out that will high light & pin point the exact issue . In a systematic Power Audit – a Power Monitoring Device – records 34 PARAMETERS *of Power in an EXCEL SHEET that further can show in more high lighted form of GRAPHS as to how their POWER USAGES are taking place in their premises.

* 34 Parameters of Power Audit

1. Harmonic Voltages : VLN Y – THD, VLN B – THD, VLN - THD
2. Harmonic Currents : Current R – THD, Current Y – THD, Current B – THD, Current THD
3. Actual Power : KW R, KW Y, KW B, KW
4. Energy units over a particular span of measurement : KWh
5. Apparent Power : KVA R, KVA Y, KVA B, KVA
6. Apparent Energy Units over a particular span of measurement : KVAh
7. Power Factor : PF(R), PF(Y), PF(B), PF
8. Currents : CURRENT(R), CURRENT(Y), CURRENT(B), CURRENT
9. Voltages Line to Line : VLL(RY), VLL(YB), VLL(BR), VLL
10. Voltages Line to Neutral : VLN R , VLN Y , VLN B , VLN

The Power Audit Report will point to WEAK & LOSS Producing areas that need to be corrected.

A Typical SUMMARY Report is produced below.

There is also provision for taking Instantaneous readings & graphs for following parameters.

Typical example of INSTANTANEOUS GRAPHS from RECORDING are as follows.

The Recording Device available that has 485 Port – can suoort upto 8 Meters , sothat recordings of all 8 meters – say with DG Generators ( to reord Diesel Generation ..) and sub circuits of the the Main Panel are also simultaneously recorded. The recorded data upto 1 ½ Year available on Server can be used for REMOTE POWER MANAGEMENT etc over long term basis.

The recorded data in addition points to Unbalances in the loads in different Phases & that can be used for rearranging the distribution evenly.

For units having different locations = you get the consolidated data to the Power Manager which hither too had been an impossible or rather very difficult task.

Some people maintain log books in Switching rooms where an attndant records some limited parameters . This meter provides 24 Hour Recording on 96 Time Points in a Day for One element all other 34 Parameters also automatically get recorded . SEE PDF attached.

It infact is a very useful Power Management tool that once demonstarated draws a user to set up permanently the Green Dot,s POWER SENSE Device.
