Fault indicator with timing control

A power system, comprising:

• a conductor for carrying current to a load;
• sensing means located in a magnetic field surrounding the conductor for sensing a trip condition in said conductor;
• electronic means responsive to said sensing means for assuming a first state in response to said sensing means sensing a trip condition representing excessive current flow and for remaining in the first state until set to a second state representing less than the excessive current flow;
• signaling means coupled to said electronic means for generating a signal only in response to said electronic means being in the first state;
• timing means responsive to said electronic means assuming the first state for setting said electronic means to the second state after a predetermined period;
• manual means for setting said electronic means to the second state before the predetermined period has expired so that said sensing means can resume sensing a trip condition in said conductor;
• said sensing means including an inductive sensor for coupling to the conductor.

A power system, comprising:

• a plurality of conductors each for carrying current to a load;
• a plurality of sensing means each for a location in the magnetic field surrounding one of the conductors;
• electronic means responsive to each of said sensing means for assuming a first state in response to one of said sensing means sensing a trip condition representing excessive current flow in one of said conductors and for remaining in the first state until set to a second state representing less than excessive current flow;
• signaling means coupled to said electronic means for generating a signal only in response to said electronic means being in the first state;
• timing means responsive to said electronic means assuming the first state for setting said electronic means to the second state after a predetermined period;
• manual means for setting said electronic means to the second state before the predetermined period has expired so that said sensing means can each resume sensing a trip condition in said conductors;
• each of said sensing means including an inductive sensor for coupling to one of said conductors.
