The present disclosure pertains to detection of abnormal, risky, or aberrant conditions in a power distribution network and to corresponding trip signals being used to trip open devices such as reclosers upstream of where the abnormal condition is detected. Detection of a missing broadband over power-line signal or of an open circuit between phases of a power distribution circuit may prevent severed conductors from causing a ground fault, therefore avoiding the possibility of fire and dangerous conditions.

The present disclosure pertains to detection of abnormal, risky, or aberrant conditions in a power distribution network and to corresponding trip signals being used to trip open devices such as reclosers upstream of where the abnormal condition is detected. Detection of open phase on a distribution circuit prevents severed conductors from causing a ground fault, therefore avoiding the possibility of fire and dangerous conditions. The voltage unbalance may be measured using an end of line relay that includes an electrical sensor or relay, a tripping mechanism, and a signal transmitter.

As air inside a building (e.g., a data center or any building that generates heat) becomes heated, it rises and is received or captured by a heat containment and then expelled from the building. The hot air is not recycle, recirculated, or re-cooled. Hot air being expelled from the building creates a pressure differential in which the pressure at the hot side of the building (where the heat containment is located) is lower than the cool side of the building. To this end, a chilling unit is installed at an opening of a building to supply cooled air at a constant rate. The chilling unit does not have an internal controller. Rather, an air conditioning (AC) unit of the building acts as an external controller. The AC unit is be set to maintain a target temperature and only runs when the temperature inside the building is above the target temperature.

Heat removal systems and methods

New heat removal systems and methods allow a combination of active and passive thermal processes for removing heat from and cooling air in environments. Systems and methods include a heat removal system including an adjustable thermal feed cold air intake system, a distribution system for cold and warm air including one or more hot aisles and one or more cold aisles, and a convection system to draw cool air through the building using a naturally-occurring convection processes to expel hot air. Misters, cooling elements, and/or freezer boxes may further cool the intake of air. A controller is programmed to efficiently manage and control the climate (e.g., temperature, humidity, air flow, pressure, air quality, etc.) within a building to minimize the use for energy for air distribution and cooling.
