Routine Test Requirements in HV CBs Routine tests are essential in the manufacturing process of high voltage (HV) circuit breakers. These tests are conducted on each unit before delivery to ensure the quality, reliability, and performance of the circuit breakers. Routine tests verify the...

Electrical Switchboards – Overcurrent protection – overload, short circuit, discrimination and cascading Overcurrent Protection Overcurrent protection comes under two main categories, Overload protection and short circuit protection. Overload protection Overload protection aims to protect conductors from the thermal effects of passing more current than...

Main switchboards are the heart of electrical supply to buildings and infrastructure, so it’s critical to specify one that’s fit-for-purpose, Standards compliant, and tested to perform. Main switchboards are commonly found in large buildings, industrial facilities, and commercial establishments where there is a substantial...

Here we will go through some of the commonly asked basic questions on electrical switchboards.     Switch board FAQs What does an electrical switchboard do? Essentially it does two things: 1) It divides up the power. In a switchboard you’ll normally have a...

High voltage (HV) circuit breakers are essential components of switchboards in electrical power systems, designed to interrupt fault currents and protect electrical circuits from damage and for control switching purposes. They are used in systems where the voltage levels are typically above 72.5 kV,...

Part 1: Standards Followed in Designing High Voltage Circuit Breakers High voltage (HV) circuit breakers are essential for ensuring the stability and safety of electrical power systems. Designing and manufacturing these devices require adherence to stringent international standards to ensure their reliability and performance...

Discrimination & Selectivity Studies What is a discrimination study? A discrimination study in an electrical system is an analysis aimed at ensuring that protective devices (such as circuit breakers, fuses, and protection relays) operate in a coordinated manner. The main objective of this engineering...
