Thyristor is also called SCR, stands for Semi Conductor
Rectifier. It is basically a four layer semi conductor
device like a transistor that is a three layer
semiconductor device.
It is generally used as a switch in the power circuit as it
can only be turned on by providing a pulse at its one of
the sandwitched layer called Gate, and the pulse is also
called firing pulse or triggring pulse. The main advantage
of this over the transistor is the it can be used into the
power circuits.

When we have earthing mesh or underground earthing network in industrial plants, weather we have NT-S or NT-C-S kind of earthing system, so eventually weather we must use 4 or 5 wire in 400 volt level (For example 3×150+70 mm2 or 5×150 mm2) in this connection I would like to know exactly the paragraph of IEC or IEEE number
