On site testing & commissioning

Start-up Testing Electrical commissioning is essential to the start up of any electrical system for the first time, regardless of size or industry. Once equipment is installed, Electrical Testing Solutions will perform visual, mechanical, and electrical tests to help ensure trouble-free energizing of the equipment.

What is included in Electrical Commissioning? Visual and mechanical inspection by factory-trained technicians verifies that equipment is in compliance with purchase specifications and design intent and that no damage occurred during shipment.The proper set up for devices, such as relays and breakers, ensures that all components are functioning correctly.Electrical testing confirms that equipment meets optimum performance standards and provides test data documentation to use as a benchmark for future testing.

Functional performance testing
Functional performance testing of emergency power systems includes testing of generators, paralleling switchgear, and ATS as well as related power distribution equipment including switchboards, panel boards, circuit breakers, metering, conductors, and any other equipment required for power distribution. A large portion of equipment testing is performed prior to energization. Typical pre-energization testing includes insulation resistance (megger), contact resistance (ductor), and overcurrent device current injection testing. Typical energized testing includes verifying the operation of metering and alarming, measuring voltage and harmonic content, confirming proper phasing, and final operational testing by verifying the sequence of operation. A variety of dynamic performance tests may also be performed including 100% block load testing, step load testing, and overload testing. Prior to the start of functional testing, it is critical to clearly define equipment settings. Complicated essential systems use multiple pieces of equipment which require coordinated settings.

Electrical testing is typically defined at the equipment level and the systems level. The electrical commissioning professional is involved in the testing of the individual pieces of equipment (generator, ATS, etc.) and then the overall system. The complexity of essential system testing depends on the needs of the facility. The following illustrates the testing and acceptance criteria for three levels of complexity.
