An improved decision tree‐based method for evaluating transient overvoltage caused by commutation failure in LCC‐HVDC systems [PDF]

open access: goldIET Generation, Transmission & Distribution, 2023
The commutation failure is the most prevalent fault in line‐commutated converter based high‐voltage direct current systems, which may result in transient overvoltage on the sending‐side system.

Transformation of Transient Overvoltages by Inductive Voltage Transformers [PDF]

open access: goldSensors, 2021
Overvoltage transients occur after any type of switching activity in a power network, such as breaker operation, fault occurrence/clearance and rapid load change. This distortion of voltage is transformed to the secondary circuit of a voltage transformer. The maximum values of such impulses may many times exceed the rated value of its secondary voltage.
