About PQWeb®

PQWeb enables utility and industrial users to view power quality data via a web browser. PQWeb eliminates the engineering effort and costs of deploying custom client-side applications.

PQWeb enables users to view downloaded and characterized power quality disturbance data. Designed with password protection for data security, the software can be used for both Internet and company intranet (local area network) applications.

By using PQWeb, a user wanting to look at events from last week can enter a password, select a site or sites of interest, and the date/time range of interest. From this, the user can select a particular event and which voltage or current phases are desired for a detailed view of the disturbance.

How It Works

The heart of PQWeb is the PQView® power quality data management system. PQView stores data retrieved from power quality measurement devices into a large database and eliminates the need for repetitive tasks such as data characterization and analysis and report writing. Until PQView arrived on the scene, instrument and event data had to be analyzed using separate applications, requiring an engineer to master each one in order to make a complete analysis.

PQView not only brings all the information together into one relational database, but it provides the power quality engineer with the means to automate both the loading of new data and the generation of monitoring reports. PQView comes with a base set of reports which provide information on raw measurements, detailed statistical analysis, and executive summaries.

From retrieved data, PQView has the ability to perform statistical studies such as trends, histograms, and correlations. These reports allow the engineer to reach all of the audiences interested in the system monitoring results. If a report format is not included in the standard templates, Electrotek can customize a report to utility and customer specifications.

From the databases created and managed by PQView, PQWeb uses a World Wide Web or company intranet server to deliver power quality data and analyses to engineers, customers, and other individuals. Data can be quickly accessed from any computer on the system using a proper user ID and password.

Power Quality Monitoring Service Option

Electrotek Concepts offers a power quality monitoring service called PowerMonitoring.com, used in conjunction with PQWeb, that automatically reports power quality data for a given site. This service is ideal for companies with remote plant locations who want to identify problems. Each night, Electrotek computers can download instrument data via telephone modem link. Options for automatic event notification, data access, and customized reports are available.
