  1. CHOLAMANDALAM MS RISK SERVICES LTD.www.cholarisk.com ELECTRICAL SAFETY AUDIT Manage Risks Profitably

  2. WHY ELECTRICAL SAFETY AUDITS • As Per FPA, UK & NFPA, US, 25% Of fires Are Due to Electrical Installations. • Indian Scenario- 40% fires due to Electrical Causes • 8 % Fatalities in Indian Factories Are Due to Electrical Causes

  3. STATUTORY REQUIREMENT • Indian Electricity Rule # 29 (1) “All Electric Supply Lines & Apparatus Shall be of Sufficient Ratings for Power, Insulation and Estimated Fault current and of Sufficient Mechanical Strength, for the Duty Which They May Be Required to Perform Under The Environmental Conditions of Installation, and Shall be Constructed, Installed Worked and Maintained in Such a Manner so as to Ensure Safety of Human Beings, Animals and Property”. (2) “The Relevant Code of Practice or the BIS If any may be followed to carry out the purpose of this Rule and in the Event of any Inconsistency, the provision of this Rule Will Prevail”.

  4. ELECTRICAL RISK MANAGEMENT SERVICES SUBJECTIVE EVALUATION OBJECTIVE EVALUATION • Earth Resistance Tests • Hotspot Measurement • IR Measurement • Overload Detection • Thermography Surveys (Tie-Up with NPC) • Physical Inspection • Statutory Compliance • Operations Review • Equipment Lay out

  5. EB PP TRANSFORMER POWER CONTROL CENTRE CRITICAL LOAD LOAD DISTRIBUTION EQUIPMENT

  6. SAMPLE TESTS • Earth Resistance • Insulation Resistance • Hotspot Detection • Load Current Measurements

  7. HOTSPOTDETECTION “All electrical failures are preceded by abnormal temperature and sound” Infra-Red Laser Guided Hot Spot Detection (Available with CMSRSL) Ultra-Sound Detector

  8. ELECTRICAL HOTSPOT DETECTION EQUIPMENT

  9. ELECTRICAL SAFETY AUDIT MAJOR FINDINGS • Elevation of buildings & structures-not considered for LP design • Protection relays- deviation from original design settings • RCCBs- wrong sensitivity,bypassing & location • Earth continuity- not tested • Use of ordinary copper wire in fuses • Statutory violations

  10. FINDINGS…. • EPM system- heavy slippage in implementation • Electrical accident investigation- Root cause rectification exercise not carried out • LHS cable ineffective installation practice • Passive fire protection inadequacies • Hotspots in LDB due to unequal load balancing • No updated reference drawing • Wrong earth pit identification • Flameproof Equipment maintenance • Tracking problem in MCCs due to dust deposits

  11. FINDINGS…. • OLTC- counter meter readings not taken • Cables added w/o considering derating factors • Insufficient baffle wall height between transformers • Wrong OTI/WTI Setting • Wrong feeder identification

  12. IER Compliance Lightning Protection ESD Hazards Shocks & Fires Protection Devices Hotspot Detection Thermography Surveys Hazardous Area Classification, review of special equipment Earthing Tests (IR, E, O/L) EPM Equipment Layout Cable Size Adequacy Fire Protection (Active & Passive) FOCUSSED ERM REVIEWS

  13. SOFTWARE AVAILABLE WITH CMSRSL • Lightning Risk Calculator (Based On Australian Standard) • Hani Rafat Risk Calculator • EXTool -SWISS Re • HAZOP, FMEA, What If, Job Safety Analysis • Risk Management Planning Software (Based on EPA, US) • PHAST & SAFETI (Tie-Up) • FPES (National Building Code)
