Transient Recovery Voltage (TRV) and Rate of Rise of Recovery Voltage (RRRV) analysis are critical grid code compliance requirements for $132\text{ kV}+$ transmission substations globally. With renewable integration, HV switchgear upgrades, and severe short-circuit duty, utilities and international engineering consultancies (AECOM, WSP, Mott MacDonald, Siemens, etc.) actively seek power system engineers who can model electromagnetic transients and evaluate circuit breaker interrupting capabilities.
