6. Earth fault protection has been applied with considerable success in limiting faults and providing quick disconnection of electrical apparatus from the supply in the event of earth fault situations A definite time operating characteristic is provided with adjustable trip sensitivity and time delay Time delay between protective units is introduced to allow the unit close to the fault to isolate the faulty circuit without causing the healthy part of the system to be de energised 4 2 Earth Leakage Systems Desirable though it may be it is impractical to provide automatic protection against electrocution as a result of direct contact with a live conductor particularly where the electrical reticulation is exposed to a humid or damp atmosphere Table 4 2 taken from IEC Standards indicates the current values affecting human beings Current mA Symptom 1 or less Causes no sensation not felt 1108 Sensation of shock not painful individual can let go at will as muscular control is not lost 8 to 15 Painful shock individual can let go at will as muscular control is not lost 15 to 20 Painful shock muscular control of adjacent muscles lost cannot let go 20 to 50 Painful severe muscular contractions breathing difficult 50 to 100 Possible 100 to 200 Certain Ventricular fibrillation a heart condition that may result in death Severe burns severe muscular contractions so severe that chest muscles clamp the

9. of Earth Leakage Protection Earth Leakage Protection Relays for use in mining applications have to be designed and tested to AS NZS 2081 3 2002 for use on fault limited systems There are two methods of protection used They are the Core Balance and the Series Neutral earth leakage protection systems The Core Balance relay performs the primary protection in an installation protecting the outlet supplying power to a machine In this application the time delay is set at instantaneous The neutral earth leakage relay is the backup relay of the installation and can have a time delay up to a maximum of 500mS 4 3 1 Balance Protection With this method the three phases are passed symmetrically through the toroid If there is no earth fault present the vector sum of the currents in a three phase supply is zero If current from any phase flows to earth the toroid flux becomes unbalanced The toroid produces an output which trips the relay A test current is injected through the window of the toroid to test the operation of the relay See typical circuit Page 16 Drawings 4 3 2 Series Neutral Protection With this method the neutral is passed through the toroid An earth fault on any of the phase conductors causes an earth current which returns through the toroid to the star point of the transformer A test circuit can connect a test resistor between a phase and earth or inject a current through the toroid as previously described The t
