How do you calculate meter multiplying factor?
Calculation of Multiplication Factor of Energy Meters
- Energy Meters are one of the important instrument to account for energy imported / exported in an industry.
- As we know that,
- Power = VICosØ where Ø is power factor.
- Therefore, an Energy Meter shall take current and voltage as an input.
- Let us take an example.
How do you calculate the electric meter multiplier?
The amount by which the voltage and current are reduced is known as the circuit multiplier. The circuit multiplier (external) is not indicated on your meter. Billing multiplier – (circuit multiplier) x (meter multiplier) = 240 x 2 = 480.
What is multiplying factor of wattmeter how it is calculated?
for finding the multiple factor of wattmeter Step3: The Multiplication Factor (MF) is: MF = (voltage range x current range x power factor)/(range of the wattmeter scale)…
What are the multiplying factor?
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 number that has only two factors, 1 and the number itself, is called a prime number.
What is multiplying factor in electrical engineering?
To arrive at actual consumption of customer, consumption registered by meter is multiplied by proportionality factor which is called Multiplying factor or MF. The ratio for CT & VT for a particular customer is designed in accordance with customer’s load requirement and load pattern.
What is multiplier in meter?
A multiplier converts the meter reading into kilowatt (kWh) units. For example, if there is a multiplier of 20 on your meter and the register goes up by 5 units, your bill will show that you have consumed 100 units of electricity.
Why do we use multiplication factor?
It helps us to measure powers up to 5-6 times the power of wattmeter to get the smallest scale value according to our convenience. It is also used in resistive current where its power factor range is from 0.5- 1.
What is multiplying factor in electric meter?
The consumption recorded by the meter is therefore less than the actual consumption of the customer in the same proportion. To arrive at actual consumption of customer, consumption registered by meter is multiplied by proportionality factor which is called Multiplying factor or MF.
