Why consumers are charged based on Kwh basis why not on
Kvah basis.

Answer / mahavir jagdev
They can be charged in Kvah only in case of DC transmision. In AC transmission due to the inductive or capacitive load the power factor comes into play, hence the effective metering is done on Kwh basis. Infact the energy company instruct the consumer whow has a lot of inductive load (motors) to put capacitor banks to keep the power factor within 0.85 region for lower powerline losses.

Answer / raj
Yeah... now industrial consumers are billed on KVAH only in Andhra Pradesh. Actually, this way of billing is the correct method to curtail low power factor problem in industries. In this case, we calculate the energy as below.
apparent energy,kvah = active power (kw)in each time block /power factor in each time block
Note : 1.presently the meters are designed for 15 minutes blocks.
2. In this billing method, the discoms dont penalize seperately for low power factor(as we already considered in thecalculation of apparent power.)
In the case of domestic, energy is billed for kwh only as it is uneconomical to place trivector meters ( as they consume less power and thier impact is very low on grid compared to industrial consumers )

Explain how you intend to work under pressure to meet up with deadline target?
i wanna know that star point in transformer becomes as a neutral on secondary side now tell me that how is that possible?because if joit the all three winding ends with each other it can b short circuited.dut it doesn't.WHY?pls Answer me in brief.thanks alot
can we keep open the secondary of current transformer?
Why should we use Star-Delta connection in step down power transformers?
why the earth terminal in three pin top is longer than rest of the two terminal and of bigger size?
WHERE to use CVT & PT.
WHAT IS MEANT BY INSULATION CLEARANCE IN VACCUM?
Why we use two wattmeter during block rotor test and no load test of 3phase induction motor? And how can we understand the neat power requirement of from this test?
When we use air circuit breaker, it has O/L protection ,time delay SC protection, Instataneous SC protection & ground fault protection. They all have some setting range. But what is the suitable/allowable setting for the above protection which will be safe for the equipment? For example-O/L protection setting have a range of (0.4,0.45,0.5,0.55,0.6,0.65,0.7,0.8,0.9,1.0)xIn Time delay SC protection have a range of (1.25,1.5,2,3,4,6,8,10,12)xIn Time delay setting is 0.02,0.1,0.2,0.3,0.4 Instataneous setting is fixed to 20xIn Gound fault setting is given 100A,300A,600A,900A,1200A This setting are for 2500A ACB. So what will be the basic allowable setting for the above protection? is there any formulae to calculate this<
What are the consequences in using existing step up transformer (primary 6.6kv/175A, secondary 480v/2405A) for step down transformer to have a 6.6kv output?
what is the relation b/w KW and KWH? plz explain with example.
