Abstract
A device for preventing arc flashes in electrical systems is provided. The device may include at least one heat sensor for measuring a temperature of an electrical conductor, and a controller operatively coupled to the at least one heat sensor and configured to arrest current in the electrical conductor if the measured temperature exceeds a predefined threshold temperature.
Claims20
An arc-flash detection device for preventing arc-flashes in an electrical system, the arc-flash detection device comprising:
- a heat sensor for monitoring a temperature of an electrical conductor;
- and
- a controller operably coupled to the heat sensor, the controller configured to receive an indication of the temperature of the electrical conductor from the heat sensor and arrest a flow of current in the electrical conductor based on the monitored temperature.
An electrical system configured to prevent arc-flashes comprising:
- a first electrical conductor, a second electrical conductor, and a third electrical conductor for distributing power from a power source to a load;
- and
- an arc-flash detection device comprising:
- a heat sensor for monitoring a temperature of the first electrical conductor, the second electrical conductor, and the third electrical conductor;
- and
- a controller operably coupled to the heat sensor, the controller configured to receive an indication of the temperature of the first electrical conductor, the second electrical conductor, and the third electrical conductor from the heat sensor and arrest a flow of current in the electrical conductor based on the monitored temperature.
A method for preventing arc-flashes in electrical systems comprising:
- measuring a temperature of an electrical conductor;
- determining whether the measured temperature exceeds a predetermined threshold;
- and
- arresting current in the electrical conductor based on the determination that the measured temperature exceeds a predetermined threshold.
