Abstract: A system for testing PLC equipment, network conditions, and protocol performance is provided. Noise measurements can be made at a single point, and protocol traffic, signal levels, and upper-layer parameters of any transmissions by other equipment on the same network are logged. Alternatively, a plurality of units located at different points in the PLC network are at least part of a distributed test system. As a result, coordinated tests can be conducted by multiple nodes, such as point-to-point network transfer function measurement and analysis, estimation of the location of noise sources and system null and resonances, receiver operating curve (ROC) measurements with actual protocol modulation, or any other suitable tests. Preferably, the test devices are able to test using a plurality of PLC protocols. In some devices, PLC protocol-specific modules can be added or removed as desired to increase, decrease or change the test device's protocol abilities.

Abstract: A method and system for connecting monitoring equipment is provided. A user is provided with instant voice feedback as they are connecting monitoring equipment. Such feedback can reduce or eliminate confusing hookup instructions and enable the user to use both hands to safely connect the equipment without the distraction of looking at hard-to-read probe markings or connection labels. The use of a voice output reduces or avoids problems of poor visibility and reduced hearing in typical industrial environments, using arc flash safety gear.

Abstract: This invention discloses a load management system for reducing the peak load in an electrical power distribution network. This invention monitors, records and reduces the peak load present in an electrical distribution network by deferring power service from and cycling power service to preselected transformer loads during periods of peak power demand. The peak load control function of the present invention is controlled by a power monitor which is located at the distribution transformer. The power monitor measures the ambient temperature and the power load on an associated distribution transformer and initiates the peak load control function whenever the product of the temperature factor and the measured load rises above a preset control point. Initiation of the peak load control function completely defers power service from a first group of low priority loads and activates a timing and switching mechanism which cycles power service among selected groups of controlled loads in a preselected order.
