Assignment : Electrical Safety Audit
Client : Taj Samudra Hotel, Colombo, Sri Lanka
Project Period : 2018
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 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 of Earthing System (Earth Electrode resistance)
- 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
- Evaluation on Electrical Housekeeping, Energy Housekeeping, Maintenance Procedures, Safety Procedures etc
- Testing of Protection Relays (ELR, EFR, PFR, Numerical Relays) for their tripping characteristics and effective operation with Secondary or Primary Injection
- Infrared Thermography survey to identify thermal anomalies under loaded conditions
- 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.
Project Period : 2021 December – 2022 April
