Common use of Tests Prior To Synchronization Clause in Contracts

Tests Prior To Synchronization. The Company, or its Contractors, shall carry out the following tests: (a) Control and operation of protective devices that interface with the System. These tests should include, but not be limited to: revision of connections and phasing; trip and close sequences; protective devices response and tripping characteristics and settings; interlocking; inter-tripping; alarms and data logging; circuit breaker operation; auxiliary and ancillary systems; batteries, chargers, uninterrupted power supplies (UPS), solar panel: short circuit current test, open circuit voltage test, maximum power test; grid tied inverter test: sine wave output test, synchronization test, anti-islanding test, power transformer test: ratio test, vector group test etc. Included is the revision of the devices’ assigned nomenclature and drawings, diagrams and connection lists. (b) Metering system: Energy meter, irradiation meter operation and accuracy test.
