5135: Electrical Utility Guide for Uniform and Consistent Practices in Defining, Monitoring and Reporting Compliance with Steady-State Voltage Levels at Points of Common Coupling

A basic attribute defining the quality of supply voltage in utility systems is the steady-state voltage at the point of common coupling. Several widely used Standards exist, in North America and elsewhere, that are referenced by electrical utilities for defining steady-state voltage levels. However, the definitions incorporated in these standards are not always consistent, and the prescribed tolerances related to steady-state voltage levels may be ambiguous. In some instances, the definitions

30134: Arrester Temperature Monitoring System Development and Potential Commercialization

The operating condition of surge arresters is oftentimes a concern after a surge or lightning event on the system. The options available in the market to determine the health of arresters are quite limited both technically and commercially. In response to this issue, the full development of a partially developed system was proposed. What was missing in the product design process was data collection software, final hardware selection, a communications system to the cloud, high current impulses, a

3319B: Additional Load Control Devices (LCDs) for Overhead Lines

In an earlier report (CEATI Report No. T003700-3304 Load Control Devices (LCDs) for Overhead Lines, Phase 1) prepared for the Wind and Ice Storm Mitigation Interest Group (WISMIG), 25 different load control devices were described and classified as either force limiting devices, force reduction devices, structure based force control methods, or load removal devices or methods. Since that report was completed, references to many new devices have been found. This report supplements CEATI Report N
