Breaker for TRV
Description:Breaker for TRV. It draws the inherent TRV envelop according to the standard IEC 62271-100. It also contains a library of breaker stray capacitances and can simulate the prestrikes, restrikes and reig... see morenitions.
In the zip file, extract and launch the .exe file. Then, start EMTP. A new library, ‘breaker’, is available. brk is the breaker.

Cross_Bonded_Cable
Description:Insulation coordination - 225 kV cross bonded cable - protection of the sheath.
In the configuration a 225 kV cross-bonded cable is connected at both ends to an otherhead line. The sheath is prot... see moreected by star-connected arresters.
The modelling used is adapted for the study of Fast-Front-Overvoltages (see IEC 60071)
A current source, with a CIGRE concave shape (See CIGRE 63 document), representing a lightning stroke has been connected to a tower close to the cable.
The case includes the modelling of the different elements of the configuration (cable, spans, arresters...).
