Temporary power connection Do's and Don'ts.

Image
Do’s : 1. Ensure taking a work permit from the site in charge and conduct a Tool Box Talk. 2. All electrical jobs to be conducted by a certified electrician. 3. Ensure all the equipment is flameproof. 4. Equipment that operates in three-phase power should have double neutral earthing. 5. The use of an Earth-leakage circuit breaker is a must for all the equipment. 6. The current rating for all equipment should not be greater than 30Amps. 7. Ensure use of proper rating Direct On Line Motor Starter in individual machines. 8. Ensure use of proper armored cables for the main power connection. 9. If there are cable lying on the road crossings or pathways should be covered and concealed to protect them from physical damage. 10. Cables without any joints should be used at all times. 11. Cables should be laid above the ground to the maximum possible extend. 12. Electrical connections should be kept clean, dry, and tight at all times. 13. Ensure all power supplies

13 test parameters to test the Turbine Oil, as per the standards.

*Test Parameters: 1. Viscosity 2. Viscosity Index 3. Flash Point 4. Pour Point 5. Demulsification 6. Copper Corrosion 7. Acid Number 8. Foam Characteristics 9. Oxidation Characteristics 10. Water Separation 11. Rust Prevention 12. Cleanliness 13. Water Content *Oxidation Stability Test :  Turbine Oil Oxidation Stability Test (TOST) is a valuable tool in order to indicate oil life for lubricants that are continuously exposed to gross water contaminations, high temperatures, and air entrainment in field service. ASTM D943 commonly referred to as Turbine Oil. Oxidation Stability Test (TOST), is widely used in the lubrication industry to evaluate the oxidation stability. *Best Practices for Steam Turbine Lubrication: 1. Keep Oil Clean, Cool and Dry 2. Install High Capture Efficiency Breathers to your Oil Respective Oil Tanks 3. Monitor returning bearing oil temperature regularly 4. Maintain proper alignment 5. Inspect for signs of foami
