Low, Medium and High Voltage Circuit Breaker Maintenance

Circuit breakers must interrupt fault currents reliably to protect people and equipment across the full voltage range. This course covers the operation, testing and maintenance of breakers from low voltage panels to high voltage substations. Delegates learn to keep switching devices dependable in tough African operating environments.
