Validating the Complete
Protection Chain
Principle
The complete protection chain is validated during a fault simulation that causes
Sepam™ to trip the breaking device.
Procedure
1 Select one of the protection functions that triggers tripping of the breaking device
and separately, according to their incidence in the chain, the function or functions
related to the programmed or reprogrammed parts of the program logic.
2 According to the selected function or functions, inject a current and/or apply a
voltage that corresponds to a fault.
3 Observe the tripping of the breaking device and the operation of the adapted
parts of the program logic.
Place the covers on the test terminal boxes when you complete the voltage and
current application type checks.
