Embodiment Construction

[0010] In one embodiment, an underground surveillance system is provided. The subsurface monitoring system preferably provides the utility with a convenient means of measuring and recording many different aspects of the subterranean secondary distribution system; however, the subsurface monitoring system may provide any suitable entity with any suitable characteristics. In one embodiment, the system is used to locate open limiters and / or faulty cables in an underground network. In another embodiment, the system monitors other parameters of the distribution system, such as voltage power quality, hazardous touch voltages, directional power flow, system impedance, and / or any other suitable parameter or value. In another embodiment, other equipment is monitored, such as transformers, network protectors, steam and gas equipment, cathodic protection systems, and / or environmental parameters such as temperature, humidity, oil and water levels, and / or any other suitable equipment or e...

Abstract

An underground monitoring system includes one or more sensors configured to monitor an underground electrical system, a processor configured to monitor the one or more sensors and an alarm device configured to send an alarm when a condition is detected by the processor.

Description

[0001] This application is a divisional application of the application with the application number 200780015356.0, the application date is March 16, 2007, and the invention name is "Underground Monitoring System and Method". Background technique [0002] High-density urban areas often use underground network grids to distribute electricity. In this case, the grid of transformers converts the high voltage (13kV or higher) feed from the substation to the secondary low voltage (below 600V, typically 120V). These secondary conductors are connected in parallel, providing a redundant link. The secondary conductor is typically 500MCM copper with rubber / neoprene insulation. A typical transformer vault or service box will contain three phase service and each phase will consist of two parallel 500MCM conductors from the network transformer. There are usually two or more sets of three-phase services, also connected in parallel. So there could be 6, 12 or 18 500MCM copper wires and eac...
