FAULT INDICATOR FOR THREE-PHASE SHEATHED CABLE |
摘要 |
A fault indicator for three phase sheathed cables includes a flexible collar unit which fits over the cable. Magnetic pole pieces within the collar unit having associated magnetic windings are aligned with the three conductors within the cable to produce signals indicative of the current level in each conductor. An alarm unit receives the signals and sounds an alarm in the event the current in any conductor exceeds a predetermined threshold level to indicate the occurrence of a fault. The voltage level of the current indicating signals may be utilized to align the magnetic core assemblies with the conductors.
