1.5 Outline of max demand measurement concept KEW6310

1.5 Outline of max demand measurement concept

In some countries, large consumers of e le ctri city w ill usua lly have a max i mu m deman d co n tra ct w ith th e pow er company. Such contract varies from country to coun try . The following is an explanation of a typical Japanese maximum demand contract.

● Maximum Demand co nt ra ct In such a contract the electricity tariff rates (i.e. for kWhr units) are based upon the consumer’s maximum power demand. The maximum demand is the maximum of average powers recorded over a 30min intervals. This is measured by the maximum demand mete r belo ngin g to the pow er comp any . Le t’s assu me th a t a pow er company has the following appli cabl e ra te s. $2 per KWhr unit for a recorded max demand 300KW during a year $4 per KWhr unit for a recorded max demand 500KW during a year $5 per KWhr unit for a recorded max demand 600KW during a year Assuming that the consumer is on the 500kW/year rate (ie. $4), and the recorded max demand during a particular day(say 15th January) is 600 kW . Then th e new applicable rate from 1st February onwards will be the 600kW/year rate (ie. $5) for the next 365 day s. If a y ear late r, on Feb ruary 1st the recorde d max imu m demand is 300kW, then the new applicable rates w ill be ch anged to 300kW/y ear ra te (i.e . $2) for the subseq uen t 365 days. However if during this period , the max demand g oes up aga in, and say 600 kW is re corded on 15th Ma rch, the applicable rates change again to the 600kW/year rate (i.e.$5) for the subsequent 365 days.

● Benefits of maximum demand control It is thus important for consumers with such contracts to monitor closely fluctuations in their power demand to ensure that their max demand limits are not exceeded and thus incur higher tariffs. Maximum Demand control is more effective in countries with higher electricity tariffs.

● Status of maximum demand contract In the past, in Japan, only consumers whose electricity supply was rated at 600kW or more used to enter into a demand contract. However, now adays pow er co mp anie s install maximu m d emand me ters a t all co nsu mers whose supply is rated 70kW or more.

● Maximum Demand measurement limitations N.B. The readings from power comp any max i mu m dema nd me te r and fro m the 6300 w ill no t match compl etely due to an obvious time-lag difference in the start of the integration period (eg.30mins) over which the max demand is taken.

● Connect the test leads and sensors to the instrument first, and only then connect them to the circuit under test.

● Never disconnect the Voltage test leads and sensors while the instrument is in use.

WARNING

● Confirm that the instrument is powered off, and then connect the Power cord.

● Connect the Power cord to the instrument first. Cord to be firmly inserted.

● Never attempt to make measuremen t if any abnormal cond ition s such as a bnorma l con dit ion s are no ted,

such as a broken Cover and exposed metal parts.

Voltage test leads and Clamp sensor connection

Follow the procedure below, and connect the Voltage test leads and Clamp sensors.

1 Confirm that the instrument is powered off. 2 Connect the appropriate Voltage test leads to the Voltage input terminal on the instrument. 3 Connect the appropriate Clamp sensors to the Current input terminal on the instrument. Match the direction of

the arrow mark indicated on the output terminal of the clamp sensor and the mark on the Current input terminal on the instrument.

* Number of Voltage test leads and Clamp sensors to be used depends on the wiring configuration under test. For further details, refer to “5.2 Basic Wiring Configuration” in this manual.

Match the arrow marks.
