5010: Evaluation of an Environmentally Benign Borate Preservative Treatment to Control and Prevent Internal Decay in Electrical Utility Poles

The relative mobility of an organically borne borate wood preservative and methylisothiocyanate in wood was evaluated under dry climatic conditions. Western red cedar and lodgepole pine stubs cut from dry pole tops were treated internally with the preservatives and the migration of the active ingredients was measured over a one-year period. Methylisothiocyanate traveled 90 cm above and below the application point within one month after treatment. The movement of the borate solution was much slow

4203: Enterprise Risk Management

As utilities mature and improve their asset management (AM) practices, risk management becomes essential to the broader AM strategy. Established standards, such as ISO (International Organization for Standardization) 5500x, incorporate risk management as a key component of broader organizational AM practices that manage operational-level risks. However, it is necessary to manage all corporate- and organizational-level risks. Enterprise risk management (ERM) allows utilities to manage these risks

5143B-09: Introduction to Power Factor Correction

ABSTRACT: As electrical systems become more heavily loaded, power capacitor banks become essential to the reliable operation of the system. Capacitor banks improve voltage control, reduce current flow, increase system capacity, and reduce system losses by reducing reactive power flow. Generally for industrial customers, the application of power factor correction capacitor banks is motivated by the desire to save money by reducing their demand charges and power factor penalties. The application o
