General Power Quality training for large users and Utility customer service Engineers 1 day

This program is most effective with managers and engineers who want a basic understanding of power quality and its economic impact on large power users

Reviews the basics of Power Quality parameters and the level of Power Quality in various countries in Asia and the USA. Includes typical costs of power quality events for many categories of sensitive customers. Understanding what 99.999999% reliability really means in electrical power. This session defines the various categories of Power Quality issues and parameters.

Reviews the EN50160 European Norm for utility power quality standard and the new Equipment PQ standard from SEMI. (Semi 47). How these standards can be used when ordering equipment to reduce the sensitivity to voltage sags.

The utility, the user and the equipment manufacturer all have different views of power quality. It takes cooperation of the three parties to find the most cost-effective solutions.

A brief history of PQ monitoring technology and a detailed review of the capabilities of the RPM power recorders and a review of the information that is available from the monitors and how it can be displayed. Examples of PQ disturbances of each type of PQ parameter.

The fundamentals of current and voltage harmonics in the electrical system. The practical perspective on sources of harmonics, measuring of harmonics, world standards for harmonics, determining when harmonics are a problem and selecting the most cost effective solution for harmonics.

Power Quality mitigation devices are available for all types of Power Quality situations. This session presents a cross section of the various technologies, manufacturers and point of use. General guidelines for selecting the most cost-effective solutions are discussed.

The fundamentals of reducing the sensitivity of loads to voltage sags and voltage transients. Each general type of load is discussed and the most sensitive subsystems or components in the load. Options of methods of reducing the sensitivity of these systems to voltage sags and transients. The testing that can be done on equipment to determine its sensitivity.

The trade off desensitizing the load vs mitigation systems.

Case Studies I of Power Quality

Examples of solving actual power quality problems, around the world. Each example, investigates a different aspect of Power Quality and the selected solution.

Using the RPM instruments to evaluate the sites, these case studies give the details of the PQ situation and the report to the customers. Available solutions are discussed in depth and a recommendation for the most cost effective solution is recommended.
