Abstract: A method of determining a fault and whether to activate an alarm includes detecting a first high impendence fault (HIF) at a first detection circuit having a first phase and triggering a variable pickup timer. The method further includes monitoring for a second HIF at a second detection circuit having a second phase for a period of time set by the variable pickup timer. The method further includes determining whether to trigger an alarm, wherein the alarm is triggered by the second HIF at the second detection circuit having the second phase being detected during the period of time and the alarm is otherwise not triggered.

Abstract: A system for automatic power outage restoration includes a conversion module, the conversion module receiving relay package input from an electro-mechanical relay package and executing code to convert the relay package input to readable output transmitted to an automatic outage restoration system. The conversion module is configured to receive the relay package input and determine whether a circuit breaker corresponding to the electro-mechanical relay package is opened manually. The conversion module is further configured to determine whether a non-fault scenario has occurred at the circuit breaker and determine whether a time from an opening of the circuit breaker has been more than a preset time.

Abstract: A system for attaching communication utility lines to a pole includes a body portion, the body portion including a plurality of attachment apertures. The system further includes a plurality of vangs located along the body portion, the vangs spaced apart and each including an aperture for receiving a communication utility line.

Abstract: A boiler system includes combustion air conduit for directing the flow of combustion air through a first air heater (e.g., A-side heater) to a boiler and flue gas conduit for directing the flow of flue gas generated by the boiler to a second air heater (e.g., B-side heater). The combustion air conduit is configured to direct the majority of the combustion air to the first air heater, and the flue gas conduit is configured to direct the majority of the flue gas from the boiler to the second air heater.
