How is DG set calculated?
Size of Diesel Generator= Starting KVA X Future Expansion X Average Use of Equipments. Size of Diesel Generator=468.7 X 1.1 X 0.8. Size of Diesel Generator= 412 KVA.
What is kVA DG set?
Kilowatts (kW) are used to measure the real electric power provided by the generator, which is used directly by appliances and equipment in the building. Kilovolt-amperes (kVA) measure the apparent power. This includes real power (kW), but also reactive power (kVAR) drawn by devices like motors and transformers.
What is capacity of DG set?
Quick Reference of Diesel Generator Set-(Part-1)
| Minimum Capacity of Daily Fuel Service Tank (AS per CPWD) | |
|---|---|
| Capacity of DG set | Minimum Fuel Tank Capacity |
| Above 62.5 KVA to 125 KVA | 225 Litres |
| Above 125 KVA to 200 KVA | 285 Litres |
| Above 200 KVA to 380 KVA | 500 Litres |
How do you calculate full load of DG?
How to calculate the full load current of a generator? For a three-phase generator, the full load current is calculated as I = 1000 × S / (√3 × V). Where, S is the generator rating in kilo-volt-ampere (kVA), and V is the generator rated voltage in volt (V).
Why DG set rating in kVA?
Essentially, the higher the kVA rating, the more power the generator produces. A kVA is 1,000 volt-amps. It’s what you get when you multiply the voltage (the force that moves electrons around a circuit) by the amps (electrical current). Kilovolt-amps measure what’s called the ‘apparent power’ of a generator.
What is the minimum load ratio for diesel generator?
30 percent load
For diesel generator sets, Caterpillar recom. mends loading the generator set to a minimum of 30 percent load for approximately 30 minutes for every four hours of light load operation.
What can a 1.5 kVA generator power?
1.5KVA rated generator can handle approx 1100 watt load. So you can run 1100 watt load safely.
How do you test for insertion loss?
During network deployment, maintenance, and trouble shooting phases, insertion loss can be measured by disconnecting the antenna and connecting an enclosed short at the end of the transmission line.
What is block loading of DG set?
Block loading means that the engine runs normally when setting up the generator, but experiences a sudden load increase that goes beyond the planned requirements. A large block load reduces engine speed, generator frequency and voltage drop, and discharging the motor shortens recovery time.
How is DG fuel consumption calculated?
If you connect an assortment of lighting and heating appliances that draw 8, 11 and 13 amps, you would have 8 X 230 + 11 X 230 + 13 X 230 = 7360 watts or 7.36 kW. That would be about 3/4 load, so the fuel consumption would be about 3 liters per hour.
