Power Rail Intelligent Analysis System (PRIAS)
- Areas of Excessive Vehicle Demand. The system employs current transducers and a GPS to locate areas where collector shoes are drawing excessive current.
- Collector Shoe Impact Points. Accelerometers and a GPS are used to locate points where collector shoes are impacting flaws in the rail system. These can cause damage to the shoe and/or the rail.
- Hot Spots. PRIAS uses thermal image technology to identify loose or failing splices, cable connections, or rail sections

5. Conductix-Wampfler engineers will comment on the causes of the identified problems and recommend the steps needed to correct the issues. See impact map below:
The graph below shows how PRIAS can zero in on specific rail areas, even individual shoes, to further analyze current demand.
The map on the right shows the points where the collector shoes are hitting an imperfection point in the conductor rail system. It could be a loose splice, ill-fitting expansion section, or some other misalignment situation. The impact map is uploaded into a hand-held PDA equipped with a GPS, which allows the user to find and inspect the impact points. The color of the impact dots indicates the severity of the impact, as shown on the map key. The impact range values can be modified depending on the situation.
