Figure 4. Three equal methods to prevent ferro resonance. WHY USE SYSTEM EARTHING LEC Support Programme for worldwide cooperation BA THS / BU Transmission Systems and Substations 57 3. DIFFERENT TYPES OF SYSTEM EARTHING In Swedish Standards (following IEC) the following earthing alternatives are given: a) Systems with an isolated neutral-point b) Coil earthed systems. c) Earthed system: -Effectively earthed system -Not effectively earthed system. In american literature, “Electrical power distribution for Industrial Plants” (ANSI/IEEE 141 1986), the following alternatives are mentioned: a) Solidly earthed (without deliberate earthing impedance) b) Reactance earthed c) Resistance earthed by low- or high resistance.

Reduction of earth fault current with a neutral-point impedance. 3 REDUCE OVERVOLTAGES The overvoltages that can be reduced through system earthing are those who depend on transient earth faults, increased neutral-point voltage and transients due to switching or lightning. Transient earth faults At occurring earth faults, especially in systems with small earth fault current, the conditions are such that the arc will be extinguished at the zero passage of the current. Afterwards it will be re-ignited when the voltage increases over the fault point again.

Depending on the voltage level and the distribution of the network this current can reach values from a few, up to hundreds of Amperes in big cable networks. The cables will give the highest capacitive current. A formula for the capacitive current IC of cables is normally stated as IC = UH/10x3 A/km, where UH is the line voltage. If the capacitance of the network is compensated with a reactor connected to the neutral point, the current through the fault point can be drastically reduced, See figure 2.
