Diesel Generator AUTO Mode: Step by Step Startup & Shutdown Procedure

Starting procedure for Diesel Generators in "AUTO" mode
  1. Ensure the Emergency Stop switch in the DG panel is in the released condition.
  2. Set the Selector switch in the DG panel to "Remote" mode.
  3. Keep the DG and EB ACB in "Remote" mode in the relevant Main Distribution Board (MDB).
  4. Verify that the lube oil level is within the allowable limit.
  5. Check the day tank diesel level (should be above 75%).
  6. Ensure the radiator water is filled up to the brim.
  7. Confirm that the batteries are in a fully charged condition.
  8. If the Transformer Circuit Breaker (CB) trips or if power fails, the DG will start automatically.
  9. Monitor and verify the following parameters:
  • DG Output Voltage
  • Load Current
  • Frequency
  • Water Temperature
  • Lube Oil Pressure
  • Battery Voltage
  • Day Tank Diesel Level
Stopping procedure for Diesel Generators "AUTO" mode.
  • If the EB (Electric Board) voltage resumes, the ACB will close automatically.
  • The DG load transfers to EB supply, and the DG breaker opens automatically.
  • The DG continues to run at no load for 60 seconds.
  • After 60 seconds, the DG switches OFF automatically.
Following these standard operating procedures ensures smooth and reliable diesel generator operation in AUTO mode, preventing power disruptions and maintaining system efficiency.

Fire Extinguishers: Types, Operation & Best Uses for Fire Classes

A fire extinguisher is an active fire protection device used to extinguish or control small fires, often in emergency situations. Typically, a fire extinguisher consists of a hand held cylindrical pressure vessel containing an agent which can be discharged to extinguish a fire. There are two operation types of fire extinguishers:  i. Stored pressure  ii. Cartridge operated  Stored Pressure  In stored pressure units, the expellant is stored in the same chamber as the fire fighting agent itself. Depending on the agent used, different propellants are used. With dry chemical extinguishers, nitrogen is typically used; water and foam extinguishers typically use air.  Cartridge Operated  Cartridge-operated extinguishers contain the expellant gas in a separate cartridge that is punctured prior to discharge, exposing the propellant to the extinguishing agent. This type is not as common, used primarily in areas such as industrial ...

Important components of a Diesel Engine - Turbocharger

Important components of a Diesel Engine Turbocharger A turbocharger can significantly increase an engine’s horsepower without adding significant weight. It enhances engine performance by forcing more air into the combustion chamber, enabling better fuel combustion. A turbocharger is made up of two main sections: The turbine and the compressor.  The turbine consists of the turbine wheel and the turbine housing.  It is the job of the turbine housing to guide the exhaust gas into the turbine wheel. The energy from the exhaust gas turns the turbine wheel, and the gas then exits the turbine housing through an exhaust outlet area. The compressor also consists of two parts: the compressor wheel and the compressor housing.  The compressor’s mode of action is opposite that of the turbine. The compressor wheel is attached to the turbine by a forged steel shaft, and as the turbine turns the compressor wheel, the high-velocity spinning draws in air and c...

Sewage Treatment Plant - Filter Feed Pumps Types and Operation And Maintenance Considerations

FILTER FEED PUMPS Filter Feed Pumps are used to draw water from the clarified water sump and pass it through the Pressure Sand Filter (PSF) and Activated Carbon Filter (ACF), which are installed in series to improve water quality. PRESSURE SAND FILTER (PSF) Working Principle: The upper layers of sand perform the actual filtration function, while gravel layers provide physical support. Specialized sand with a specific particle size is used to trap solid impurities present in water. The particles get entrapped in the spaces between sand grains, eventually blocking water flow. When the pressure drops beyond a set limit, the sand is cleaned by backwashing with water. Backwashing reverses the flow, fluidizing the sand bed and removing lighter solid particles as waste. Operation And Maintenance Considerations Filtration is followed by a short backwash sequence. The filter requires backwashing when the pressure drop across the filter reaches 0.5 kg/cm². Best practice: Backwash once per shift,...
