Project: T183709 #30/134

This proposal is to develop and potentially commercialize an Arrester Temperature Monitoring System (ATMS) that allows for continuous monitoring of arresters and offers utilities a better method of assessing their health, using wireless temperature sensors to continuously assess the temperature of an arrester.  The goals of this project are as follows:

Stage 1: Utility Application Feasibility Study (4 months)

Since this method of arrester health assessment has never been used before, there is a learning curve for both the developers and potential users. Stage 1 of the project is designed to ensure that this method is feasible in harsh environments where the systems does not negatively impact the subject arrester and that the components of the system are not sensitive to the high voltage substation environment. Selecting the method of data transmission, storage, and the level of data to transmit will also be a part of this phase. Once the hardware and software objectives are determined, then a pilot installation at a convenient utility substation will be setup. Throughout the first stage, the data analysis methods will be developed that results in adequate performance to flag a failing arrester. The scope in this stage ends with the Go-No-Go decision as to feasibility in the utility substation environment

Stage 2: Field Trials (6-12 months)

The scope of this stage is make final selection of hardware and software to be part of the longer term ATMS. Package the system, develop the installation procedures, and install at several locations. Demonstrate the system wide data acquisition and display. Preferably locate a failing arrester identified by other means and check the operation of this ATMS on this arrester.
