Load Bank Reactor/Inductor/Chokes are used in conjunction with back-up power generators which need to be run on a regular basis. Performing this function without or with little load may lead to a phenomenon called“wetstacking” which shortens the life of the diesel engine that runs the generator. The load bank is often specifically built to reflect the exact electrical characteristics, resistance, capacity and reactivity of the facility in question.
This series of reactors are usually used in the resistive-reactive load banks for testing and maintenance of large AC power systems at rated kVA. Resistive-Reactive Load Banks offers a 0.80 power factor load and is designed for testing large generators, switchgear, transformers and UPS systems.
1. It is used to simulate inductive load in a system.
2. It is also used to compensate capacitive current in a system.
3. Inductive load must be connected across phase in a system.
