Initially, the focus of the project will be on the switching of 33kV rated shunt reactors (based on the cost and existing experimental facilities), but other voltage levels may be considered.

Develop guidelines for reactor switching  transient recovery voltage (TRV) simulations at 33kV (and other voltages )

Make recommendations for circuit breaker rating and mitigation options for inclusion in a company policy document.

If the outcomes are useful, there could be the possibility of extending the project to cover higher voltages and series reactors.

This project will be deemed successful if a more economical solution is determined for reactor switching.
