Efficient Grid Operation and Maintenance with Simulation Apps

Jing Zhang, NARI Group Corporation, China

Engineers at NARI Group Corporation developed the Cable Condition Analysis Expert System App, based on their electrical and structural multiphysics model, to accurately predict cable faults and improve troubleshooting efficiency. The simulation application enables field technicians to directly enter data from cables and select the type of fault, modifying the underlying multiphysics model on the fly and allowing them to determine what caused the fault. The application makes the work of NARI's field technicians more efficient by letting them confidently assess if a cable needs to be repaired or replaced and predict if a fault will happen.

The Cable Condition Analysis Expert System App is used to improve troubleshooting efficiency and predict cable faults.
