Answer: Very fast-front overvoltages (VFFO) are caused by switching
... For GIS or MTS, disconnector switching is common in substations operation. During the closing and opening of a disconnector, a number of pre-strikes and re-strikes occur due to the low speed of disconnector compared to the circuit breaker. Each strike generates VFFO. Therefore, the switching of the ...

Broadcast television systems
Broadcast television systems are encoding or formatting standards for the transmission and reception of terrestrial television signals. There were three main analog television systems in use around the world until late 2010s (expected): NTSC, PAL, and SECAM. Now in digital television (DTV), there are four main systems in use around the world: ATSC, DVB, ISDB and DTMB.
