CERTILEC / Electrical protection testing

Verify the protection response.

Targeted tests compare settings, trip logic and expected results.

Client situation

Relays to verify after installation, setting changes or unexpected operation.

Review approved settings, plan tests, perform secondary injection and check the trip path.

Result sheets, measured times, deviations and test report.

Electrical protection testing

Collect parameters and compare with approved coordination studies.

Identify functions and thresholds based on relay, drawings and site conditions.

Test relevant protection functions with suitable equipment.

Check signals, contacts and trip path under safe conditions.

Measure response against tested function settings.

Results, deviations and recommendations for correction or retest.

Industrial LV/MV networks: fault and selectivity studies inform approved settings before relay and trip-path testing.

IEC 60909 may guide short-circuit calculations; tests follow relay functions, approved settings and site procedures.

CERTILEC / Electrical protection testing

Specific tests, calculations and deliverables are agreed after reviewing your needs and site conditions.
