How does DG set work?
A diesel generator is actually a machine that converts mechanical energy (produced by an in-built combustion engine) into electrical energy. Engine – Being the primary component of the diesel generator set, the engine supplies the mechanical energy which is later transformed into electrical power.
What are the DG parts?
The main components of a diesel generator are:
- Diesel Engine.
- AC Alternator.
- Base frame, usually with a tank.
- Control Panel, maybe with a Automatic Transfer Switch (ATS)
- Circuit Breaker.
- Radiator.
What is DG earthing?
Earthing or Grounding of Diesel Generator Plant is important to ensure correct operation of the plant and safety of the people who work over there. Generator neutral (star point) is to be connected by insulated earthing conductor through the neutral earthing link or device to main earthing bar.
What is DG maintenance?
DG A- Check this check is preventive Maintenance of DG sets(1000-1500KVA). 1. A-check is done on daily basis here we check: a) oil level b) coolant level c) gauge valve level d) check for any leakage. e) cleanliness of DG set. 2) B-check(done after 300hrs of cycle or 6 months whichever is earlier. )
How does DG start?
First, air is blown into the generator until it is compressed; In this way, it starts combustion and causes the generator to start up. Thus, the generator starts to produce the necessary electrical energy to be distributed according to the needs of the equipment connected to it or the place / space that it will supply.
What is the function of DG?
A diesel generator (DG) (also known as diesel genset) is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. This is a specific case of engine-generator.
Is generator grounded?
All portable generators need to be grounded in order to be safe. But, whether you need to do anything special to ground your generator depends on how it was designed. Most modern portable generators are designed such that the metal frame around the generator acts as the path of least electrical resistance.
Why DG set is rated 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.
How do I start DG?
1. Push Button Start/ Manual Mode:
- After pressing the start push button and turning the ignition key toward start position, the battery is connected to the starter which cranks the engine shaft resulting in the start of the engine.
- This arrangement can also be provided in small DG sets.
How do I start DG manually?
5.1 FOR STARTING DIESEL GENERATOR SET IN MANUAL MODE
- Check fuel level into the diesel service tank.
- Check battery voltage on the alternator panel.
- Check coolant level into the radiator.
- Start lubricating pump by pushing its “ON” button on the breaker panel.
Do you need to disconnect batteries from DG set?
Batteries are to be disconnected, in case of persons working on the DG Set. 21. Disconnect all harness connections to the PCC & Engine control system before doing any welding work on DG set. Controller & PCB can get damaged due to welding currents.
How does DG synchronizing panel system to be start DG?
Brief Technical Description DG Synchronizing Panel System to be Start DG as per required load. Basically it can be operated By Auto Mode and Manual Mode. As per required Load we can change Consumption mode it Night Mode and Day Mode.
What to do when installing a DG set?
Earthing of the DG Set is recommended and please refer to the specific recommendations. 16. Keep tools & other metallic objects away from uncovered batteries. Use tools covered with vinyl electrical tapes or suitable non – conducting material to avoid possibility of shorting battery connections while working near batteries. 17.
