Key Components and Concepts:
- Switchgear:
A combination of electrical disconnects, fuses, and/or circuit breakers used to control, protect, and isolate electrical equipment.
- High Voltage (HT):
Refers to electrical systems operating at higher voltage levels, typically above 1000V.
- Automation:
The use of technology to perform tasks with minimal human intervention, such as remote monitoring, control, and protection of switchgear.
- Substation Automation:
A broader concept encompassing the automation of all equipment within a substation, including HT switchgear.
Benefits of HT Switchgear Automation:
