Commissioning works

Commissioning Work, carried out by the electrical equipment manufacturer, is the final set of activities for putting equipment into operation, including checking, adjusting and testing all systems to ensure their correct and safe operation. It includes the following:

Pre-launch checks:	Adjustment of equipment:	Comprehensive tests:	Commissioning:
visual inspection of equipment for compliance with the project and standards; verification of the quality of installation (contacts, grounding, insulation); measurement of insulation resistance, activation of circuits.	setting the parameters of relay protection (RPA), automation (ABP), control systems; calibration of sensors, meters, current/voltage transformers; programming of microprocessor devices (PLC controllers).	testing of equipment under load; simulation of emergency modes (for example, short circuit) to test the protection; synchronization with dispatching systems (SCADA).	phase-in of live equipment; control of operating parameters (current, voltage, temperature); preparation of acceptance certificates; instruction on operation and maintenance; transfer of documentation (passports, test reports, schematics).
