Save Time and Improve Accuracy When Troubleshooting

Answer Modules® are proprietary algorithms that convert raw power quality event data into precise answers to determine the source and cause of the disturbance. These unique tools enable users to save time and improve accuracy when troubleshooting power quality problems. The Dranetz HDPQ Xplorer 400, Dranetz HDPQ Xplorer, and Dranetz HDPQ Guide include the following Answer Modules: Sag Directivity, Power Factor Correction Capacitors and Motor Quality Annunciator Panel. Answer Modules® are options for use with PQView DE software, and are available for specific applications. Please review the product description for a summary of available modules.

Features

Answer Modules® Available Options for PQView DE Software

Sag Directivity SW Module: SW-SAG The RMS Voltage Sag Directivity Answer Module arms you with the ability to identify and locate the problem. Voltage sags can be caused by faults on the power system or by internal events, such as the start-up of large loads. Knowing the location of the fault – either inside the facility or in the distribution network of the power supplier – is the starting point to resolving the problem and protecting your operation quickly and cost-effectively. The AnswerModule detects a voltage sag event, identifies its characteristics, and determines the direction of its location relative to the monitoring point. Located within PQView DE software, the RMS Voltage Sag Directivity Answer Module enables users to quickly determine whether the fault occurred upstream or downstream of the monitoring point. PF Cap Directivity Answer Module: SW-PFCAP This Answer Module automatically identifies transients as originated from power factor correction capacitors. You can instantly track down the offending capacitor bank and develop a solution to the problem (new switching schedule, controlled switching, or changing equipment). Generic Modbus driver: SWMDBUS-DE The Generic Modbus driver Answer Module adds communications with virtually any Modbus compatible device to PQView DE, including those from Dranetz and other manufacturers.

Voltage Sag Directivity Answer Module The Voltage Sag Directivity Answer Module automatically identifies a voltage sag event and determines the direction of its location relative to the monitoring point. Power Factor Correction Capacitors Power Factor Correction Capacitors provide voltage support and correct power factor on distribution systems. While capacitor switching is common and normal, it can cause transients that disrupt machinery, adjustable speed drives and process controls.
