Mesh Grounding Design for GIS: Importance, Standards, and Analysis Tools

1. Introduction Grounding systems in high-voltage substations—especially Gas Insulated Substations (GIS)—play a critical role in ensuring operational safety, equipment protection, and electromagnetic compatibility. Among the grounding approaches, mesh grounding is the most widely adopted due to its effectiveness in dissipating fault currents and limiting hazardous potentials. This article explores the importance of mesh grounding in GIS, the relevant standards, the...

Design Guide – Neutral Transformer Earthing in High Voltage Generators

Introduction Neutral earthing is a critical design aspect of high-voltage (HV) generators, ensuring safe operation, effective fault detection, and minimized damage during earth faults. Two common methods are neutral earthing resistors (NERs) and neutral grounding transformers (NGTs). For HV generators, NGTs are often preferred. This article explores the reasons for this preference and provides a detailed calculation example for...

Understanding ISO 8528-1: Generator Set Ratings, Overloads, and Duty Classes

I. Introduction In power generation systems, particularly those using reciprocating internal combustion engines, selecting the correct generator rating is critical for performance, reliability, and compliance. The ISO 8528-1 standard defines performance criteria, rating classifications, and operational guidelines for such AC generator sets. This article provides a comprehensive overview of ISO 8528-1, focusing on rating definitions, overload allowances, and duty classes,...
