Medium Voltage Load Banks
The Trystar MV Series Load Bank delivers the industry’s most rugged, high-capacity solution for medium-voltage generator and turbine testing. Designed for 5kV or 15kV applications, each turn-key package integrates a dry-type step-down transformer and low-voltage load bank on a substation-style skid for easy installation. Built with galvanized steel, stainless fasteners, and a powder-coated finish, the MV Series withstands harsh outdoor conditions, with sealed heated compartments protecting power and control circuits. Operator safety is enhanced with E-Stop, fault indicators, and automatic load dump, while optional digital metering and remote monitoring provide advanced control. Forklift channels simplify handling, making the MV Series a reliable choice for mission-critical power validation.
Features
- High-Capacity Medium-Voltage Testing – Engineered for 5kV and 15kV diesel generators and gas turbines, with power ratings from 1000 kW to 2500 kW (custom sizes available).
- Turn-Key Skid-Mounted Package – Combines a dry-type step-down transformer and low-voltage load bank on a single, pre-wired skid—simplifying setup and lowering installation costs.
- Rugged Outdoor Construction – Galvanized steel enclosures with a durable powder-coat finish, stainless hardware, and heated sealed compartments protect against weather, moisture, and condensation.
- Operator Safety Built-In – Features include Emergency Stop, illuminated controls, smart fault indicators, and automatic load dump to disable load during faults or outages.
- Dry-Type Transformer Advantage – Lightweight, reliable transformer design avoids fluid leaks, reduces maintenance, and lowers long-term operating costs compared to oil-filled alternatives.
- Advanced Monitoring & Control – Optional digital power meter with Modbus connectivity provides 16 load parameters for PC, PLC, or data logger integration.
- Efficient Cooling System – High-performance, direct-driven blower motors deliver consistent airflow to protect resistor elements, with overload protection and current-limiting fuses for reliability.
- Reliable PowerDyne™ Resistors – Non-corrosive resistance alloy with stainless supports and ceramic insulators ensures long life, stability, and dependable outdoor performance.
- Simplified Installation & Handling – Forklift channels, modular layout, and service-friendly design make installation, cooling, and maintenance efficient and straightforward.
