Assignment : Electrical Safety Audit
Client : ASK Engineering Services (Pvt) Ltd
Project Period : 2022/23

APCL comprehensively studied Pegasus Reef Hotel’s Electrical Installations for their safety against effects to invaluable humans, livestock and expensive equipment by analyzing compliance requirement to BS/EN 7671 (IET Wiring Regulation) and other respective IEC standards.

  • Visual & Aerial Inspection of Medium Voltage System (Transformers, Switchyard)
  • Visual Inspection on Service entrance, Alternative supply sources (i.e Generator), Electrical Distribution Boards/ panels, distribution paths, Final circuits etc
  • Degree of insulation levels of feeders & circuits (via Insulation Resistance test)
  • Inspection, Testing & Review of Earthing System
  • Testing of Residual Current Circuit Breakers (RCCBs) for ensuring fault protection
  • Testing of Earth Fault Loop Impedance & Prospective Short Circuit Current
  • Coordination among Overcurrent Protective Devices (OCPD) and Cables
  • Overcurrent and Earth Fault protection coordination
  • Testing of Protection Relays (ELR, EFR, PFR, Numerical Relays) for their tripping characteristics and effective operation with Secondary or Primary Injection
  • Lightning Protection System (LPS) compliance to IEC 62305 by examining coverage & condition of External Lightning Protection Systems and effectiveness of Internal Overvoltage Protective measures (i.e. SPDs)
  • Other additional studies etc.

In addition, APCL prepared Single Line Diagrams (SLDs) of existing Low Voltage installation to provide comprehensive system information

Following the study, APCL consultants and engineers presented the Electrical Safety Audit findings and system improvements recommended for enhanced protection.
