THE ANSWER IS SHOWN BELOW.
Step-by-step explanation
1.
- If protection fails or is absent, lightning that strikes the electrical system introduces thousands of kilovolts that may damage the transmission lines, and can also cause severe damage to transformers and other electrical or electronic devices.
2.
- No, Technically, in case of a lightning strike "all the earth pits must be connected" to provide equipotential bonding.
3.
- The energy in a lightning strike is typically in the range of 1 to 10 billion joules.
- This energy is released usually in a small number of separate strokes, each with duration of a few tens of microseconds (typically 30 to 50 microseconds), over a period of about one fifth of a second.
- The great majority of the energy is dissipated as heat, light and sound in the atmosphere.
4.
- The types of lightning arresters are rod, sphere, horn, multi gap, electrolyte, and metal oxide.
- The types of surge arrestors are distribution, low-voltage, station, DC, neutral protection, fiber tube, signal, network, etc. This arrester can be used as a surge arrester.
5.
The power loss can check by several methods given below:
- Using a voltage signal as reference.
- Compensating the capacitive element by using a voltage signal.
- Capacitive compensation by combining the leakage current of the three phases.
- Third order harmonic analysis.
- Direct determination of the power losses.
