Transformers & Switchgear Basics
What transformers and switchgear do, how their health is judged, the difference between isolators, contactors and circuit breakers, and how to behave safely around substations. For technicians, operators and anyone whose work takes them near HV/LV equipment.

Чему вы научитесь
- Explain what a transformer does and distinguish oil-filled from dry-type designs.
- Describe the key transformer health factors: oil condition, temperature and loading.
- Explain the three jobs of switchgear — switching, protection and isolation.
- Distinguish an isolator, a contactor and a circuit breaker and state what each may and may not do.
- Describe conceptually how a protection relay detects a fault and trips a breaker.
- Follow substation access and awareness rules as non-electrical staff, including oil containment and SF₆ awareness.
