What is the SIGMA PC Software?
The SIGMA PC System runs on Windows machines and is used to control up to 14 SIGMA 2 controlled Load Banks. If multiple Load Banks are connected, load is distributed on the resistive and/or reactive Load Banks proportionally based on the Load Bank size. This ensures that all operational Load Banks are sharing the load. From the PC System, the load can be applied manually or automatically (using a pre-programmed test sequence). Load can be entered in kVA (or kW), or expressed as a percentage of the supply on test. For an inductive Load Bank, a fully variable power factor can be set from 0.0 cos phi to 1.0 cos phi.
