Fault protection system for power supplies that use ferro-resonant transformers |
摘要 |
A fault detection system for use in power supply systems using ferro-resonant transformers is presented. Current sensing means are used to sense the current flowing in the ferro-resonant circuit associated with operation of the ferro-resonant transformer. A fault detection circuit, powered by its own power supply connected to the primary source of power, monitors the sensed current and signals any significant change therein. A fault condition in any of the secondary circuits of the transformer causes the ferro-resonant current to change, and upon sensing this change, the fault detection circuit disconnects the primary of the transformer from the source of power.
