How do you calculate the multiplying factor of an energy meter?

How do you calculate the multiplying factor of an energy meter?

Power = VICosØ where Ø is power factor. Therefore, an Energy Meter shall take current and voltage as an input. Current and voltage input is extended through metering core of Current Transformer (CT) and metering core of Potential Transformer (PT).

What is the formula of multiplication factor?

Step 3: The Multiplication Factor (MF) is: MF = (voltage range × current range × power factor) / (range of the wattmeter scale).

What is multiplying factor in electricity bill?

It is the factor that is used to multiply the reading of the energy meter to get the actual energy consumption. If the M.F is 10, and the energy meter reading difference (the difference is used because energy meter reading is cumulative) is 45 for a period. The actual energy used for the period is 45×10 = 450 KWH.

How energy is calculated in energy meter?

Your electric meter records electricity usage in kilowatt-hours. In simple terms, 1 kilowatt hour = 1,000 watt-hours. For example, if you turn on a 100-watt light bulb for 10 hours, the energy usage is calculated as 100 watts x 10 = 1,000 watts (or 1 kilowatt hour).

What is a multiplying factor in maths?

The numbers that we multiply are the factors of the product. Example: 3 × 5 = 15 therefore, 3 and 5 are the factors of 15. This also means: A factor divides a number completely without leaving any remainder. For example: 30 ÷ 6 = 5, and there is no remainder.

What is a meter multiplier electricity?

For electric meters, this is the ratio of the customer’s total load to the amount of the load flowing through the meter. Residential, farm and small commercial meters usually have a multiplier of one. That means all of the electricity used flows through the meter.

What is meter multiplier?

Meter Multiplier. For electric meters, this is the ratio of the customer’s total load to the amount of the load flowing through the meter. Residential, farm and small commercial meters usually have a multiplier of one. That means all of the electricity used flows through the meter.

How does energy meter calculate kWH?

Just like the odometer on your vehicle that shows the actual distance travelled by the vehicle, electricity meter shows the amount of electricity that is used. So a 100-Watt bulb if kept on for 10 hours will consume: 100 x 10 = 1000 Watt-Hour = 1 Kilowatt-Hour (kWH) = 1 units (on your meter).

What is multiplying factor in percentage?

MF (Multiplying Factor) corresponding to x% increase is 1 + (x/100) and x% decrease is 1 – (x/100). If a number for e.g. 200 is increased by 30% what will be the final number? = 260. so here 1.3 is the multiplying Factor corresponding to 30%.

How is the multiplication factor of an energy meter calculated?

Multiplication Factor of Energy Meter is calculated as below Multiplication Factor = (External CT Ratio x External PT Ratio) / (Meter CT Ratio x Meter PT Ratio) You can find the meter CT and PT ratio in the manufacturer manual. Usually both the ratios are 1.

What does multification factor mean on electrical meter?

If the C.T used in the line is actually 200/1 & P.T is 33000/110 V, then there is no MULTIFICATION FACTOR means it is 1 not 0. ( Multiplication Factor , in short MF ). You can read the consumption directly from the meter itself as the meter is calibrated for the very ratioes.

How are energy meters used in power plants?

Energy Meters are one of the important instrument to account for energy imported / exported in an industry. In Power Generating Stations, the cumulative reading of such energy meters are used for the calculation of total Million Units (MUs) of energy exported. On the basis of MUs, total revenue generated by the Station is calculated.

How is the reading of an energy meter used?

In Power Generating Stations, the cumulative reading of such energy meters are used for the calculation of total Million Units (MUs) of energy exported. On the basis of MUs, total revenue generated by the Station is calculated. Thus reading of Energy Meter is quite important to be recorded, accounted and audited.
