ConclusionsThe influence of electrodeposition parameters on the magnetic and magneto-impedance properties of electrodeposited CoP/Cu composite wires was investigated systematically. Our results reveal that the GMI effect can be optimized in the composite wires through tailoring the electrodeposition parameters of the CoP magnetic layer.

In order to protect against neutral failures, 18th Edition states that the earth impedance between the vehicle charging earth and the true ground (or earth), for chargers fitted outside the home, must be under 200 ohms to minimise any voltage developed between the two and ensure correct operation of an RCD.It can be possible to achieve this 200 ohms earth impedance by sinking one or more

The most common methods of measuring the resistance …
· When an earth electrode system has been designed and installed, it is usually necessary to measure and confirm the earth resistance between the electrode and “true Earth”. The most commonly used method of measuring the earth resistance of an earth electrode is the 3-point measuring technique shown in Figure 1.
