PRORING – Advanced Protection System for High-Voltage Motors and Large-Scale Power Applications
Maximum grounding integrity and reliability for the most demanding industrial applications.
The PRORING solid (non-split) version is an uncompromising solution engineered for large-frame electric motors, generators, and turbines operating in the High Voltage sector. This product combines a monolithic construction with the latest conductive technology to create an impenetrable barrier against destructive shaft currents.
Key Innovations and Characteristics:
1. Monolithic Construction for Maximum Conductivity
The non-split version of PRORING is designed for installation during the assembly of new machinery or major overhauls. The absence of mechanical joints ensures a perfectly uniform distribution of the electrical field and the lowest possible impedance across the entire circumference of the shaft.
2. Steered Charge Technology
As with our most advanced systems, PRORING utilizes intelligent geometry in the arrangement of its conductive elements. This system actively forces a directional flow of electrons, instantaneously dissipating high-frequency (HF) charges directly to ground, thereby preventing the formation of destructive electrical arcs inside the bearings.
3. Latest Conductive Technology Without "Bottlenecks"
In the PRORING series, we have utilized high-purity, high-conductivity fibers integrated into the metal housing through a proprietary surface modification process. This eliminates the contact resistance that limits the effectiveness of charge dissipation in standard solutions, especially at higher voltage levels.
4. Resistance to Extreme Operating Conditions
Featuring a robust housing and precisely embedded rows of high-conductivity fibers, PRORING is built to operate in the harshest environments—from power plants to heavy processing industries. The design ensures stable electrical parameters throughout the service life, regardless of the shaft's rotational speed.
Applications and Benefits:
- High-Voltage Motors: Ideal for large-frame units where induced shaft voltages reach critical levels.
- Generators and Turbines: Capable of safely discharging high-amplitude currents, protecting expensive components from electrical discharge machining (EDM).
- Full VFD Compatibility: Optimized for operation with modern variable frequency drives that generate intensive HF interference.
- Extended Drive Longevity: Radically extends bearing life cycles, eliminating the need for frequent and costly maintenance.
Why Choose PRORING Solid?
For the largest drive units, where every microsecond of grounding system response time is vital, the PRORING solid version is unparalleled. It is an investment in the highest available standard of electrical safety, eliminating the risk of failure where reliability is the priority.
