Utilities are governed by standard in terms of their system availability and quality of power. These standards are becoming key factors in determining pricing and network investment. It is thus important to fully understand the introduction of new equipment in the network. It is important that volt drop, harmonics and ferroresonance are studied in the network when fault current limiting devices (FCLD) is be considered.
One of the first criteria that is checked in any network is the voltage at various junctions and customers. must have low impedance in order to reduce the voltage drop across it during normal operation. This would reduce the energy losses and be a strong motivation factor in the selection process of FCL mitigation measure. This is the key factor in the choice of passive devices while active ones will generally not have this problem.
The low or no energy consumption and better voltage quality of active devices will be weighed against the high costs of the device and installation. FCLD location will have an effect on the voltage regulation in the network.
