Voltage fluctuations are unavoidable when operating electrical supply networks. While the rotating mass of power generators seems to remain unfazed by load changes, every change in current causes voltage fluctuations, of greater or lower severity. The effects of this occurrence are especially noticeable in inefficient supply networks and at the end of long branch lines.
The operation of certain, often complex, electrical equipment frequently requires the provision of an operating voltage with narrow tolerances and a high degree of long-term stability, to ensure uninterrupted, reliable operations.
The following automatic and magnetic voltage stabiliser series described represent robust, reliable equipment, the concept for which has proven reliable in continuous usage at numerous places of operation under even the most difficult operating conditions.
