Generator Protection
GENERATOR PROTECTION

Protect the generator without losing sight of the complete system.

TURNER ECS reviews, tests and modernises generator protection as part of the wider control, breaker and electrical architecture.

OPERATIONAL CHALLENGE

Modernisation starts with the behaviour the asset must preserve.

Selectivity

Protection must isolate the correct fault without unnecessary loss of generation.

Clear evidence

Events, disturbances and time records must support investigation.

Recurring assurance

Settings, trip circuits and breaker interfaces require controlled testing.

TECHNICAL SCOPE

Engineer the complete route, not an isolated component.

Relay functions

Differential, overcurrent, earth-fault, voltage, frequency and power functions.

Interconnection

Loss-of-mains, mains decoupling and utility protection.

Breaker circuits

Trip-circuit, breaker, interlock, current-transformer and voltage-transformer checks.

Settings

Coordination against generator capability, utility agreements and islanding philosophy.

Testing

Secondary injection, trip verification and recurring schedules.

Evidence

Fault recording, communications, events and Global Positioning System or Network Time Protocol synchronisation.

INTEGRATION & VALIDATION

Prove how the updated system will behave in operation.

The exact engineering and compliance route depends on the installed architecture, customer standards, applicable authorities and approved responsibility boundaries.

Protection philosophy

Connect functions, settings and trip paths to the operating philosophy.

Grid evidence

Support Grid Code and utility verification with controlled records.

System coordination

Align generator, breaker, plant and network protection.
