To calculate the power factor (pf) of a 1010 kVA diesel generator (DG) set, you can use the formula:
[ \text{Power Factor (pf)} = \frac{\text{Real Power (kW)}}{\text{Apparent Power (kVA)}} ]
First, determine the real power (kW) output of the DG set, which can be obtained from the manufacturer's specifications or by measuring the actual load. Then, divide the real power by the apparent power (1010 kVA) to find the power factor. Typically, a power factor of 0.8 to 0.9 is common for DG sets.
Rating for DG set and any of electrical machines is calculated in KVA. KVA is calculated as KW/pf. One can calculate the required KVA for DG set with this formulation: (KW/pf)/load rate. For example KW=110, pf=0.8 and one loads the DG at 75%, so KVA= (110/0.8)/0.75=185 KVA.
DG set is designed for 0.8 lag power factor. if it fall below this, we can used proper rating capacitor to improve this. what happens if we run the DG at .6 pf
You need to fix a certain amount as basic salary if you want to deduct PF. set a minimum number as basic salary and calculate PF on it. The remaining amount based on piece rate can be added a different component in the persons salary
There is no rebate on PF. You only get tax benefits for PF contributions equal to the amount contributed subject to an upper limit of 1 lakh.
How do you calculate voltage drop for starting motor current
Rephrase your question so that it makes sense.
A Payroll Management Software is used to calculate salary of employees and calculate deductions such as PF, PT, ESIC and Income tax. Payroll software takes attendance of the month and calculates salary as per the defined values and formula set. Arrears, Bonus, Reimbursement. winhrmpayroll.com
as per government go release wages in that mention basic we calculate pf on basic
No. It is set at a minimum of 12% of the employees basic salary
no
Calculate the ampereage at .8 pf and take a breaker of 150% of ampere nd set the over current protection at 125% of full load current.
Since watts = volts times amps times 1.73 times power factor (for a three phase motor): W = E * I * 1.73 * PF Solving for I: I = W / (E * 1.73 * PF) Lets say your motor has a PF of 0.85: I = 10000 / (415 * 1.73 * 0.85) I = 16.39A If this is for your homework (I hope not) and PF is not given, then you will substitute 1.0 for the PF and, of course, arrive at a different answer!
