What is high voltage switchgear?

High voltage switchgear is an integral part of the electricity grid which is used to control, protect and isolate electrical equipment in a power system. Saifa Khalid, Analyst-II at PTR Inc. explores the critical technology and how it has evolved in the digital age of energy.

Why is a high-voltage switchgear system more efficient?

A high-voltage system can be more efficient as it requires less current to transmit the same amount of energy. High-voltage switchgear and electrical systems are generally only used at utility substations or large industrial or health/education campuses.

How energy storage system supports power grid operation?

Energy storage system to support power grid operation ESS is gaining popularity for its ability to support the power grid via services such as energy arbitrage, peak shaving, spinning reserve, load following, voltage regulation, frequency regulation and black start.

Why is electrical switchgear important?

Electrical switchgear protects expensive equipment from damage caused by short circuits, power surges, and outages, which can result in costly downtime and loss of business. Switchgear also ensures a smooth transition to backup energy sources during an outage.

How can digital technology help control high voltage switchgear?

Remote monitoring of HV switchgear and real-time data collection to identify potential issues and schedule maintenance during off-peak hours is also enabled by digital technologies. Centralised control system is another technology that paves the way for monitoring and control of high voltage switchgear.

What is the monitoring content of intelligent high-voltage switchgear?

The monitoring content of the intelligent high-voltage switchgear includes partial discharge monitoring, ultrasonic wave, geoelectric wave and temperature sensor to collect corresponding data, and then transmit it to the intelligent data acquisition gateway through wired mode.
