Introduction
The Philippine Electrical Code (PEC) 2017 Part 1, aligned with international best practices, mandates the Power System Study (PSS) as an integral part of the electrical design process for ensuring safe, efficient, and reliable operation of electrical installations. This article explores the PEC clauses relevant to power system study requirements, its scope, applications, and the scenarios where...
Arc Flash Hazard Mitigation: A Comparative Analysis of IEC and IEEE/ANSI Standards
1. Introduction
Arc flash hazards pose serious risks to personnel, equipment, and facility operations in both industrial and utility-scale electrical systems. Mitigation of these hazards is governed by international standards which provide frameworks for calculation, design, protection, and personnel safety. Two major frameworks dominate global practice: the International Electrotechnical Commission (IEC) and the Institute of Electrical and Electronics...
Provisions for Lightning Protection in the Philippine Electrical Code (PEC 1 – 2017)
Introduction
Lightning strikes pose a significant risk to structures, sensitive electronic systems, and life. In the Philippines, where thunderstorms are frequent, the need for reliable lightning protection systems (LPS) is essential. While the Philippine Electrical Code Part 1 (PEC 1 - 2017) does not provide a comprehensive design methodology for LPS, it outlines key safety requirements, bonding provisions, and...

TECHNICAL NOTE : Scope of the Philippine Electrical Code (PEC) on Fire Detection, Fire Protection, and Fire Alarm Systems
1. Introduction
The Philippine Electrical Code (PEC) 2017 Part 1 provides minimum safety standards for the installation of electrical systems, including those associated with fire detection, fire protection, and fire alarm systems. While the PEC does not define performance or detection thresholds, it governs the electrical wiring, protection, and interconnection of these critical life safety systems.
This technical note summarizes...
