Standard Operating Procedure (SOP) for Earth Pit Resistance Measurement Fig - Earth Resistance Tester Wiring Objective To measure the earth pit resistance accurately using an Earth Resistance Tester. Equipment Required Earth Resistance Tester (with four terminals: P1, P2, C1, and C2) Two terminal rods (for current and potential measurement) Measuring tape Hammer (for driving rods into the ground) Procedure Step 1: Preparation Clean the Earth Pit Properly – Remove any debris or obstruction around the earth pit to ensure proper connection. Check the Earth Resistance Tester – Ensure the tester is in good working condition. The tester should have four terminals: P1, P2, C1, and C2 . Check if the pointer reads zero when the equipment is not in use. If required, adjust the zero adjustment screw to set the pointer at zero. Step 2: Connection Setup Short terminals P1 and C1 and connect them to the earth pit electrode whose resistance needs to be measured. Position the terminal r...

5S Methodology Objective, Identify, reduce and eliminate waste Enhance teamwork Enhance operation effectiveness in a better working environment Form the basic advanced model for Productivity and Quality Improvement. As each 5S management techniques begins with an S, this approach has been named 5S. Fig - 5S Methodology SORT To sort and systematically discard items that are not needed in the workplace. SET IN ORDER To arrange necessary items in a neat and systematic manner so that they can be easily retrieved for use and to return after use. SHINE To clean and inspect the workplace thoroughly so that there is no dirt on the floor, machines and equipment. STANDARDISE To maintain a high standard of workplace organisation by keeping everything clean and orderly at all times. SUSTAIN To train people to practise the 5S system continuously so that it becomes habitual and ingrained in the culture of the organisation.

Types of Cleaning Agents Cleaning agents are the most important in Housekeeping department in their day to day operations to keep the room clean. Taski is a specific products which is mostly used in HK industry, these cleaning agents are used with specific codes to understand better in HK industry eg: R1, R2, R3 ('R' Stands for 'Room Care'.). Lets see here Taski products with details Fig - Types of Taski Chemicals and Usage TASKI R1 Bathroom cleaner and Sanitizer Area to be cleaned: All bathroom surfaces, sink, tub, tiles, floors and fittings Dilution: For cleaning : 20 ml in 1 ltr water For sanitizing : 50 ml in 1 ltr water Using: • Spray directly on the surface to be cleaned • Leave for 2 seconds • Scrub if necessary and wipe surface with clean and dry cloth • Replace cloth regularly TASKI R2 Area to be cleaned: All types of floor and walls How to Dilute: Normal soiling: 20 - 40 ml in 1 ltr. water Heavy soiling: 50 ml in 1 ltr. wat...

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...

Diesel Generator Maintenance Checklist A-CHECK (DAILY MAINTENANCE) Cleaning - Clean engine and premises. Checking Engine Oil Level - Ensure oil is between H and L marks on the dipstick, top up if required. Checking Coolant System - Verify coolant level in radiator, top up with premix coolant if needed. Inspect belt condition. Checking Fuel System - Inspect fuel strainer, clean breather on fuel tank, drain sediments/water from fuel water separator, and refill fuel tank at end of the day. Checking Air System - Monitor vacuum indicator for air restriction (red band). Inspect air filter sealing and condition. Other Checks Check for leaks and rectify if needed. Run engine and record all parameters. Checking Battery System Voltage should be above 26V. Ensure battery terminal tightness (use an insulated spanner). Check specific gravity using a hydrometer (1.21-1.24 or 1220-1250). B-CHECK (EVERY 225-250 HRS. OR 6 MONTHS, WHICHEVER IS EARLIER) Changing Lubrication Oil - Warm up and sto...

Diesel Generator Question & Answer - 1 1. Why should a DG set not be run with full fuel in the tank? Answer: A full fuel tank creates improper pressure across fuel lines, leading to excessive black smoke emission. 2. Why is bleeding required? Answer: The fuel system requires air bleeding under the following circumstances: The engine has not been operated for a long time. A fuel element has been replaced. The engine was started without opening the fuel cock and has run for some time. The feed pump is not functioning properly. There is leakage from fuel pipes or fuel filters. 3. How to remove Air Lock? Answer: Air lock can be removed using an air primer as per the steps below: Loosen the bleeding screw of the primary fuel filter. Unscrew the priming knob of the fuel pump, move it 10 to 15 times, until fuel flows out without air bubbles. Tighten the air vent screw and repeat for the secondary fuel filter. Finally, loosen the air vent screw of the fuel injection pump and remove air b...

Residual Current Device (RCD) Protection What is an RCD? A Residual Current Device (RCD) trips the circuit when it detects an earth fault current, providing an extremely effective form of shock protection. How RCDs Work The amount of current flowing through the phase (line) should return through neutral. An RCD continuously monitors the current flow and detects any mismatch between the current flowing through phase and neutral. If an imbalance is detected, the RCD trips the circuit within 30 milliseconds, preventing potential electric shock or fire hazards. Common RCD Ratings and Their Applications 30 mA (milliamps) – Maximum permissible for personal shock protection. 100 mA – Provides enhanced shock protection, though not as sensitive as 30 mA. 300 mA – Maximum permissible for fire protection. Why Use RCDs? Prevents electric shock by cutting off power within milliseconds. Limits fire risks caused by earth faults. Detects faults early, preventing damage to electrical installations. P...
