Commissioning, testing gensets using resistive/reactive load banks

摘要

When examining the key differences between resistive and resistive/reactive load testing-and why the latter is necessary-it is important to focus on addressing a facility's emergency power generation system as a whole by testing the entire system to identify system-wide weaknesses at the time of commissioning and at periodic test intervals to comply with regu-latory agencies (see Figure 1). Reactive load testing is primarily important at health care facilities, data centers, life safety, and mission critical applications where the need to demonstrate the capability to provide electrical power as intended is prescribed by regulatory standards and codes specified by the designers. Examples of typical emergency power sources include gas- and diesel-fueled reciprocating engine generators, liquid- and gas-fueled turbine generators, rotary UPS, and battery UPS systems.
