Electrical shock detection device and methods

A method for detecting a stray electrical current comprising the steps of:

• placing a plurality of probes at least partially in a fluid medium;
• collecting a plurality of measurements by repeatedly measuring the electrical potential difference between two of said plurality of probes;
• applying at least one filter that reduces the amount of noise in said plurality of measurements;
• analyzing said plurality of measurements to detect the presence of a predetermined frequency;
• and
• transmitting, if said predetermined frequency is detected, an alarm to warn of a stray electrical current.

A shock detection device comprising:

• a plurality of probes for at least partially disposing in a fluid medium;
• and
• a control unit comprising:
• at least one analog-to-digital signal converter in electrical communication with at least one of said plurality of probes;
• at least one audio-visual alarm;
• and
• a processor operably coupled to said at least one converter and to said at least one audio-visual alarm,
• wherein said processor is operable to transmit a signal from one of said plurality of probes to another of said plurality of probes, to calculate the conductivity of said fluid medium based on the attenuation of the signal received by said another probe, to determine a maximum detection distance based on said conductivity, to measure an electrical potential difference between two of said plurality of probes, to analyze a plurality of said measurements to detect the presence of a predetermined frequency, and to transmit an alert signal to said at least one audio-visual alarm upon detecting said predetermined frequency.
