Time for an Update: Why the Philippine Electrical Code Needs to Align with the Latest NEC Edition

Executive Summary The Philippine Electrical Code Part 1 - 2017 (PEC1:2017) has served as the national standard for electrical installations for nearly a decade. Modeled after the U.S. National Electrical Code (NEC) 2017, the PEC1:2017 introduced important safety and design improvements over its predecessor. However, as of 2025, the NEC has already advanced through two subsequent revisions: NEC 2020 and...

Fault-Ride Through (FRT) in Renewable Energy Systems

1. Introduction The increasing integration of renewable energy sources (RES) such as wind and solar into power systems requires these sources to contribute to grid stability during disturbances. One critical requirement is Fault-Ride Through (FRT), which ensures that generators remain connected during voltage disturbances caused by grid faults. This article outlines the concept, relevance, and standard compliance requirements of FRT...

Operational Testing of High Voltage Electric Motors

1. Introduction High voltage (HV) electric motors-generally rated at 1kV and above-are critical assets in industrial and utility-scale applications. Their continuous, reliable performance is essential for plant productivity and safety. To ensure optimal function and early fault detection without interrupting production, a suite of online (operational) tests is employed. These tests monitor electrical, thermal, and mechanical conditions while...

Ground Fault Detection Methods in Power Systems: Techniques, Applications, and International Standards

Ground faults are one of the most common and potentially damaging disturbances in electrical power systems. They occur when a phase conductor unintentionally comes into contact with the ground or any grounded surface. Accurate and timely detection of ground faults is crucial to ensuring personnel safety, equipment protection, and system stability. This article outlines the key methods used in detecting...
