Siemens SIPROTEC 5, Manual

Overview
Various tests have to be performed for commissioning to warrant the correct function of the device.
For tests using secondary test equipment, make sure that no other measurands are locked in and trip and
close commands to the circuit breakers are interrupted, unless otherwise indicated.
Secondary tests can never replace primary tests because they cannot include connection faults. They provide a
theoretical check of the setting values only.
Primary tests may be done only by qualified personnel who are familiar with the commissioning of protection,
monitoring and fault recording systems, with the operation of the system, and with safety regulations and
provisions (switching, grounding, etc.).
Switching operations also have to be performed for the commissioning. The described tests require that these
be capable of being performed safely. They were not conceived for operational checks.
Functional tests must be repeated at regular intervals and include:
•
Current and voltage measured values
•
Binary Inputs and Outputs
•
Trigger settings
•
Communication interfaces
•
Fault recording and failure indications
