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 the Encore® Series Software, the RMS Voltage Sag Directivity Answer Module enables power customers 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 and points to the direction of the capacitor switching transients. The GPS-based precision time stamps in the Encore Series let you combine reports from many locations, so you can instantly track down the offending capacitor bank and develop a solution to the problem (new switching schedule, controlled switching, or changing equipment).

VAR Verifier Answer Module: SW-kVAR

(Requires SW-PFCAP – PF Cap Directivity SW Module)
Beyond traditional power quality issues such as transients, there are fundamental concerns about whether or not capacitor banks are actually energized when they are switched on. In the past, this type of information required a physical inspection of the bank. Now, with the kVAR ChangeVerifier AnswerModule, you can determine whether the bank is energized and if kVAR generated by the capacitor bank is evenly distributed across all three phases.

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.

Motor Quality Annunciator Panel
There are various electrical parameters that either adversely affect the health of an electrical motor or are an indication of the health of the motor. The Dranetz Motor Quality Annunciator Panel displays those parameters in a single color-coded screen.

Dranetz HDPQ Xplorer 400, Dranetz HDPQ Xplorer, Dranetz HDPQ Guide,PX5-400 PX5, PG4400, and Encore Software. Sag directivity, CapSwitch and Motor Quality Annunciator Panel are all included with Dranetz HDPQ Guide, Xplorer, Xplorer 400, and the PX5-400, PX5, and the PowerGuide 4400. Answer Modules® are NOT available for the Dranetz HDPQ Visa or the PowerVisa. Answer Modules® are available for Encore Software as required.
