Systems and methods for determining electrical faults

摘要

Certain embodiments of the invention may include systems and methods for determining electrical faults. According to an example embodiment of the invention, a method is provided for determining electrical faults. One method can include providing switch circuitry including at least one first switch detector resistor in parallel communication with at least one switch; providing terminal board circuitry including at least one terminal board resistor in parallel communication with the switch circuitry and in communication with a power source; receiving a power source reference; comparing a field voltage value to a generated reference voltage value, generating a comparison value output based at least in part on the comparison of the field voltage value and the generated reference voltage; and determining one of a plurality of field conditions based at least in part on the comparison value output.

1. A system comprising:
a power source; a first circuitry comprising:
a switch; anda first resistor coupled to the power source and the switch in a first arrangement whereby a first current propagates through the first resistor when the switch is in an open condition; at least one interconnecting wire; a second circuitry coupled to the first circuitry via the at least one interconnecting wire, the second circuitry comprising:
a second resistor coupled to the power source in a second arrangement whereby a second current is propagated through the second resistor; and an acquisition circuitry coupled to the second circuitry, the acquisition circuitry comprising:
a current-to-voltage converting circuit that provides a first sensing voltage that is proportional to the first current and the second current; anda voltage comparator configured to receive the first sensing voltage as a first input and further configured to receive a reference voltage as a second input, and to output a first comparison value indicative of one of a normal condition or a fault condition of at least one of the first circuitry, the second circuitry, or the at least one interconnecting wire.
