How do you calculate feeder loss?

How do you calculate feeder loss?

Loss Load Factor = 0.8 x LF2 + 0.2 x LF Load Factor = Actual load/Maximum Load 9. Commercial loss = Total energy sent-(Total energy billed +Technical loss) The above methodology is applied in the two feeders to estimate the theoretical loss in the feeder.

How do you calculate power loss?

The formula to calculate the line loss is P = I × V. If a current ‘I’ flows through a given element in your circuit, losing voltage ‘V’ in the process, then the power ‘P’ dissipated by that circuit element is the product of that current and voltage.

How do you calculate technical loss?

1. HT line losses = 1.05 x (265 × 2) x 6.18 x 0.54 x 0.1361 /1.5 x 1.15 x 1.15 x 2 = 831 KWh.
2. Peak power losses = 3 x (3 × 63 + 3 × 260 + 1 × 1380) /1.15 x 1.15 x 1000 = 3.0.
3. LT Line losses = 3 x 0.1361 x 8760 = 3315 KWh.
4. Total technical losses = (831+ 3315 + 10424 + 6490) = 21061 KWh.

What are non technical losses?

These are the losses that occur due to unidentified, misallocated or inaccurate energy flows. They can be thought of as electricity that is consumed but not billed. In the case of non-technical losses the end user is unknown or the amount of energy being consumed is uncertain. …

What is feeder loss?

Feeder loss indicates the signal loss caused by various devices that are located on the path of the antenna to the receiver. Any device using an external antenna for service provision at either the base station side or terminal side must consider feeder loss.

What is line loss measured in?

Calculate line loss as the square of your current multiplied by your calculated resistance: P(loss)=I²R Using Step 1, you may substitute for I, leaving an equation of: P(loss)=P²R/V² This presents a fundamental axiom of electrical theory: line loss is greatly decreased by an increase in voltage.

How do you calculate line drop?

Voltage drop of the circuit conductors can be determined by multiplying the current of the circuit by the total resistance of the circuit conductors: VD = I x R.

How do you calculate 11kV?

For sure there are wire manufacturers that provide datasheets on their product hinting to current carrying capabilities. Take a 11kV/415v, 500KVA distribution system. Then maximum current on HV side = 500/{sqrt(3) * 11} = 26.24 A. maximum current on LV side = 500/{sqrt(3) * 0.415} = 695.6 A.

What is T and D losses?

The T&D losses represent electricity that is generated but does not reach intended customers. India’s T&D losses have been over 20 per cent of generation, which is more than twice the world average. The ideal level of T&D losses ranges between six to eight per cent.

What is AT & C losses?

AT&C Losses The concept of Aggregate Technical & Commercial losses provides a realistic picture of loss situation in the context it is measured. It is combination of energy loss (Technical loss + Theft + inefficiency in billing)& commercial loss (Default in payment + inefficiency in collection).

What is feeder cable?

Feeder cables are used to supply power from one part of a facility to another, from point A to point B. Perfect for providing temporary power service during construction or to supply power to specialized equipment. Primary feeder cables typically run between main switchboards and power distribution transformers.

What is feeder cable in telecom?

Feeder Cable Introduction Feeder cable is normally regarded as a thick electrical cable. The cable is made from a number of different elements that when together enable the coax cable to carry the radio frequency signals with a low level of loss from one location to another.

How to calculate the KVA of a feeder?

1 Calculate the amps of each feeder and the total load [Sec. 220-2 (a)]. 2 Calculate kVA of feeders 1, 3, 5, and 6, based on supply voltage and load. To do this, multiply the current by the voltage. 3 Calculate amps of each feeder, based on supply voltage and load. 4 Determine which 90°C MV conductors to use.

Why is it important to know income over feed cost?

Income over feed cost (IOFC) can be a critical metric when evaluating a farm’s profitability and the sustainability of a current or proposed feeding program. During times of low milk prices, understanding your costs can be crucial to a farm, effectively riding the wave to the next high or low in the milk price storm.

When do you need to do a load calculation?

When there is a question as to how to do a certain type of load calculation, there is a chance something in one of the examples in Annex D could help. For example, a calculation is needed for 12 single-phase ranges supplied by a 208Y/120-volt, three-phase, 4-wire service.

How are load calculations organized in Article 220?

Article 220 contains load-calculation procedures for all types of occupancies, but they are not organized by types of occupancies. The organization of this article is in its scope (220.1).
