SVERKER900 - Testing impedance based protection
The impedance measurement schemes are widely used for protection of different assets within electric power systems. Relay protection devices utilizing such schemes are benefiting from continuous monitoring of both voltage and current quantities within the protected circuit and the calculated impedance value is employed to determine whether the circuit is operating in a normal condition or not.

DCM305E Earth Leakage Clamp Meter
Since there is no such thing as perfect insulation, if any conductor is raised to a potential above that of earth some current is bound to flow to earth from that conductor. The amount of current that flows is dependent on:Voltage on the conductorThe capacitive reactance between the conductor and earthResistance between conductor and earthCurrents that flow to earth are called leakage currents and are usually very small values, typically < 1 mA. However the amount of current that is required to cause distress or harm to a human being or animal is also small, these currents must be limited by circuit design to safe values.If this is not possible, then a 30 mA RCD (residual current device) or 30 mA RCBO (residual current device with overload protection) should be fitted for personal protection.
