• 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.

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
