"Building on the incredible success of the IDM, the world’s #1 installed and most preferred fault recorder, we introduce its successor, the IDM+.”
Key features:
- Utilizes the most accurate measurement chain including sampling rate of 512 samples per cycle and analog resolution of 20 bits on current channels
- Option of traveling wave fault location with accuracy of ±60 meters [±200 feet]
- Full solid state device and high reliability - all data stored on CompactFlash
- Advanced iQ+ client-server multifunction master station software
"We have developed a flexible, modular platform to perform a variety of power system monitoring functions - Digital Fault Recording (DFR) and Dynamic Disturbance Recording (DDR) with options for Phasor Measurement Unit (PMU), Class A Power Quality (PQ) and Fault Location (FL) - impedance as standard or option of TWS FL can all be offered within this one device.”
iQ+ Master station software
Partnering the IDM+ is the advanced iQ+ client-server multifunction master station software. One master station application to manage all QUALITROL substation monitors (including legacy devices), i.e; IDM+, IDM and DFR family, FL-8, FL-1, TWS and DSFL fault locators and INFORMA PMD-A and QWAVE family of power quality monitors.
