Overvoltage protection and insulation coordination
2015The surge arrester at the line entrance must be installed for the protection from fast-front overvoltages. The selected surge arrester in the simulation model has a sufficient performance for the assumed lightning strike and other conditions. The standard rated lightning impulse withstand voltage can be selected from 1,050, 1,175, 1,300, and 1,425 kV ...

Matrix converter with overvoltage protection circuit
Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference, 2010In this paper a matrix converter with a special circuit is presented. It works so that no overvoltage can be produced by an interruption of an input phase when operating with inductive load current. Also a switching off of one or more semiconductors of the inverter matrix can not produce the high voltage spikes by using the overvoltage protection ...

Transient overvoltage protection for UPS applications
2011 IEEE Trondheim PowerTech, 2011Uninterruptible Power Supplies (UPS) are used to ensure a continuous and reliable supply to critical loads. Different UPS technologies are available, offering different levels of load protection and power conditioning. This paper discusses various UPS topologies and operating modes, identifying the paths over which a surge or transient voltage may ...

Overvoltage transient protection network design
Proceedings of the International Conference on Electromagnetic Interference and Compatibility, 1999Transient over-voltages caused by lightning, couples on to data communication or instrumentation signal lines and introduce serious fault alarm conditions and damage instrumentation electronics. Protection circuits to minimise the transient over-voltage are commercially available for variety of installation requirements.
