In this example we simulate a pool with a faulty underwater lamp that is a source of leaking electricity. The pool walls are covered with low conductivity ceramic tiles, so the only sink for the electricity is the grounded ladder. A dummy is immersed in the pool with both hands touching the ladder.
Electromagnetic clutch consists of an electromagnet (which includes the solenoid and the core), a steel rotor and non-magnetic insert between them.
At longer power lines wires are transposed according to the transposing scheme. Each of the three conductors must hang once at each position of the overhead line. On transmission lines of 110-500 kV rate one complete cycle of a transposition should be carried out if the line length exceeds 100 km. The transposition should be carried out so that total lengths of transmission line parts were approximately equal. The length of our line is 120 km. The distance between transposition points is 40 km.
