AnswerModules are available only with the Signature System™ providing power managers with unequalled access to practical answers—not just data— to the most troubling power quality problems.

Answer Modules Can Iidentify RMS Voltage Sags, Capacitor Transients, and Radial Line Faults

Available AnswerModules address the most common and potentially disruptive issues confronting power managers: RMS voltage sags, capacitor transients, and radial line faults.

Three AnswerModules are available for use with the Signature System™:

1. The RMS Voltage Sag Directivity AnswerModule automatically detects voltage sags, the most common cause of power disturbance. Once detected, the AnswerModule characterizes the sag and determines whether it originated upstream or downstrem from the monitoring point. If a DataNode is located at the utility service entrance, the Signature System can automatically detect whether the sag originated within the facility or from the utility system.

2. The Radial Fault Locator AnswerModule identifies the source and location of faults, calculating the distance from the monitoring point to the fault, allowing managers to immediately dispatch linemen for repairs and eliminating the need for linemen to “walk the line.”

3. The CapSwitch AnswerModule automatically identifies capacitor switching transients, providing the information managers need to track down the problem capacitor bank and develop timely solutions, whether those solutions require new switching schedules or changes to sensitive equipment.

4. The RBM (Reliability Benchmarking Methodology) AnswerModule allows users to measure and benchmark utility service reliability. The Advanced Event Characterizer/Reliability Benchmarking AnswerModule™ , located within the Signature System InfoNode, employs proven algorithms to extract and analyze captured events, characterize them, and compile indices for historical analysis. It characterizes the event in terms of voltage peak, frequency, duration and depth of the voltage sag, as well as other factors and enables you to classify the event based on a user-defined table of severity and/or IEEE Standard 1159.
