0327: CPF: Hydro-Electric Coating Strategies for Corrosion Prevention

Many utilities have a large number of painted assets that are typically of high capital value, in particular penstocks and the primary turbine water passages. The corrosion protection systems/coatings for these assets are largely based on the coating technologies of the 1940s to 1960s. These coatings are now reaching the end of their technical life and due to Occupation Health and Safety (OHS) and environmental concerns these coatings are no longer acceptable.This technology review presents the

3275A: CPF: Standardization of OHTL Inspection Data Collection (Mobile Applications)

This report details consensus specifications and requirements for inspection data collection for routine patrols of Overhead Transmission Lines (OHTLs). This is part of a multi-phase project to accommodate the potential interests of different utilities. For example, some utilities already have mobile IT in place, or are in the process of developing such systems, and therefore are primarily interested in refining their existing inspection data collection requirements (based on the information dev

7011: Heat Recovery System Used in a Hospital to Preheat Domestic Water

A heat pump is a machine or device that extracts heat from one location and transfers it to another. Heat pump technology is applied increasingly as a method to improve systems efficiency. Based on the second law of thermodynamics, known as the Carnot thermodynamic cycle, this technology uses a heat source, a heat sink and a refrigerant. The heat pump transfers heat by circulating the refrigerant through a continuous cycle of evaporation and condensation. A compressor pumps the refrigerant b

7007: Study of Refiner Motor Failures - Phase 1

A survey of 51 pulp mills was carried out to investigate the frequency of failure and causes of failure in large refiner motors. Failure rates due to mechanical and electrical components were compared. As well, failure rates for motors subject to periodic reversal were compared to those for single direction motors."

3106: Use of Lightning Arresters to Protect and Improve Outage Performance of Unshielded Lines

The application of surge arresters to protect and improve the lightning performance of unshieldedtransmission lines is analyzed by means of a statistical simulation tool developed in the MATLABenvironment, in conjunction with EMTP‐RV. The lightning performance of three unshielded lineswith different configurations and different voltage levels is evaluated. The use of line surge arrestersto improve the line performance was examined for gapped as well as gapless arresters. In everycase, the possib

3090: Selection and Specification Guide for HV Surge Arresters

The selection of appropriate overvoltage surge protection is a primary concern when providing insulation co-ordination of complex, costly systems and apparatus installed on the high-voltage network. The overall aim is to reduce the cost and disturbance caused by insulation failure and resulting system outages to an economically and operationally acceptable level. As the use of products and equipment vulnerable to voltage surges and spikes continues to increase, the requirement also increases for

7019: Power Quality Energy Efficiency Guide

Power quality has become the term used to describe a widerange of electrical power measurement and operational issues.Organizations have become concerned with the importanceof power quality because of potential safety, operational andeconomic impacts. Power quality is also a complex subject requiring specificterminology in order to properly describe situations andissues. Understanding and solving problems becomes possiblewith the correct information and interpretation.This Power Quality Referenc

5142D: Harmonic Distortion Level Evolution at Residential PCC in North America, Phase IV

In 2000 [24] and 2008 [8], surveys were performed in Canada to measure the harmonics caused by domestic loads. Each survey was performed over one year in single week intervals for each location; together confirming observations made by Professor Alexander Emanuel in 1995 [3] which revealed that the growth rate of harmonics can be up to 0.35% per year.Although harmonic orders 9 and 15 were the only orders identified as being critical in the 2008 survey [8], the safety margin allowing for addition

0320: CPF: Industry Survey of Turbine Lubrication Oils Used at Hydroelectric Power Plant: Performance and Problems

Turbine oils are essential to the operation of hydroelectric power generating equipment. They are used for lubricating and cooling purposes, and for operating the generators' speed governor system. The types of oils historically used in hydro turbines are no longer readily available on the market in the United States and Canada. Currently available turbine oils are blends of a different type of base oils and new additive packages, which may not be fully compatible with in-service oils. The
