Modelling and identification for reduction of overvoltage transients

IEE Proceedings - Electric Power Applications, 2003
The main problems that appear when using a long cable connection between a Variable Frequency Drive (VFD) and the AC motor are over-voltages and bearing currents. The last one concerns especially EMC, while the over-voltage transients can be fatal to the motor.

Simulation of Transient Over-voltage from Energization of Unloaded Transmission Line [PDF]

, 2018
In power systems, energized transmission line when slightly loaded unloaded, or open-circuited (disconnected), the voltage at the receiving-end will often be greater than the voltage at the sending-end. This phenomenon is known as Ferranti Effect.

A novel embedded voltage‐clamped circuit for multilevel modular converters submodule to suppress very fast transient overvoltage

High Voltage
The submodule in multilevel modular converters experiences a very fast transient overvoltage (VFTO) during switch operation of gas‐insulated switchgear, which also results in overvoltage on power devices, such as thyristors and insulated gate bipolar ...
