Very large capacity, portable Load Bank System consisting of multiple units, each rated 5.0MW, capable of parallel operation to form very large systems of up to virtually unlimited capacity. Medium voltage to 34.5kV. PLC-based digital control. Each load bank trailer equipped with digital control system and local operator interface. Each trailer networked such that entire trailer can be controlled from a single station. Any system of paralleled trailers can be controlled from a single station, either at one trailer or at a remote station.

General
| • | Each 5.0MW Portable Trailer Load Bank consists of four (4) principle elements, factory packaged as a system: Low Voltage Load Bank Module, Transformer Module, Trailer, and Dgitial Controller. |
Low Voltage Load Bank Module
| • | Total Capacity: 5.0MW, 1.0 power factor |
| • | Voltage: 480vAC, 3-phase, 3-wire (from transformer) |
| • | Frequency: 60 Hertz |
| • | Load steps: 50KW step resolution |
Transformer Module
| • | 5.0 MVA, dry type |
| • | Medium voltage delta: 480Y/277vAC, 60 hertz |
| • | Medium voltage, 1200A, 3-pole, manually operable, fixed mounted, fusible disconnect |
| • | Fused low voltage outputs |
Trailer
| • | Highway semi-trailer, “low-boy”, tri-axle, 48-foot |
Digital Controller
| • | PLC-based digital control. Each load bank trailer equipped with digital control system and local operator interface. Each trailer networked such that entire trailer can be controlled from a single station. Any system of paralleled trailers can be controlled from a single station, either at one trailer or at a remote station. |
Power Distribution Switchgear
For connection of system of multiple load banks to generator switchgear:
| • | Outdoor, freestanding metal-enclosed power distribution switchgear consisting of multiple cubicles |
| • | 15kV vacuum circuit breaker for each load bank trailer |
| • | Transformer Protection Relay for each breaker |
| • | Instrumentation potential and current transformers |
| • | Low voltage motor starter and control power cubicle |
| • | Network PLC control |
| • | Touchscreen operator interface |
