Understanding Transient Recovery Voltages Seminar. This hands-on course gives an overview of the origins of transient recovery voltages (TRV) for: terminal, short-line and out-of-phase faults; capacitive current switching: shunt capacitor banks, cables and lines; and inductive current switching: shunt reactors and unloaded transformers. The derivation of the TRV values found in the IEC and IEEE standards, now harmonized, will be explained.
When a high voltage circuit breaker interrupts a fault or load current, the voltage across its terminals goes almost instantaneously from a low arc voltage to a much higher recovery voltage. This latter voltage is known as the transient recovery voltage or TRV for short.
 
The characteristics of TRVs are dependent on the type of current being interrupted, the system grounding arrangement and the reaction of the associated circuit to the change of state. The reaction involves power frequency components with superimposed oscillations dependent on circuit damping and travelling wave effects.

This hands-on course (bring a calculator) gives an overview of the origins of TRVs for the following cases:
  • Terminal, short-line and out-of-phase faults
  • Capacitive current switching: shunt capacitor banks, cables and lines
  • Inductive current switching: shunt reactors and unloaded transformers
The derivation of the TRV values found in the IEC and IEEE standards, now harmonized, will be explained.
