The Dranetz HDPQ® family of Power Quality, Demand and Energy instruments is the latest in a long line of industry
leading products from Dranetz. The Dranetz HDPQ family is comprised of four portable instruments, with the
difference being the availability of Wi-Fi communications, advanced intelligent AnswerModules, high speed transient
capabilities, 400Hz monitoring and other advanced features. The Dranetz HDPQ instruments are: Visa, Guide, Xplorer
and Xplorer-400. Each is a successor to the Dranetz PowerVisa, PowerGuide, PowerXplorer and PowerXplorer-400.
The Dranetz HDPQ merges the state-of-the-art power monitoring capabilities you expect from Dranetz, with 'best in
class' communication capabilities to provide users with a revolutionary monitoring experience. Each instrument has a
built-in 7-inch color wide screen LCD user interface for monitoring setup and data review. By putting operator safety
first, the Dranetz HDPQ also enables users to review data and change settings remotely from virtually any Smartphone
or Tablet mobile device, along with traditional PC and Mac laptops and desktops. Just hook up the instrument, close
the cabinet doors to 'safe' the environment and use either a free 3
Android App via Ethernet, Wireless, or Bluetooth for remote control from anywhere with connectivity to the
instrument.

Summary of Contents for Dranetz HDPQ XPLORER

  • Page 1 77Compatible NTRODUCTION The Dranetz HDPQ® family of Power Quality, Demand and Energy instruments is the latest in a long line of industry leading products from Dranetz. The Dranetz HDPQ family is comprised of four portable instruments, with the difference being the availability of Wi-Fi communications, advanced intelligent AnswerModules, high speed transient capabilities, 400Hz monitoring and other advanced features.
  • Page 2 HDPQ A RANETZ PPLICATIONS Voltage The Dranetz HDPQ family is a series of portable Dranetz HDPQ has (4) differential AC/DC voltage monitoring instruments that is intended for temporary channels rated 1000V CAT III/600V CAT IV. Voltage and semi-permanent Power Quality, Demand, and channels are labeled A, B, C, D and are connected to Energy surveys.
  • Page 3 HDPQ ACKAGING INSTRUMENTS Enclosure All Dranetz HDPQ instruments are packaged in an IP50, ergonomically designed ABS plastic enclosure with a All Dranetz HDPQ instruments have a built-in 7-inch protective rubber boot. The HDPQ enclosure provides (measured diagonally) color LCD touch display with an LED backlight.

  • Page 5 HDPQ IRING ONFIGURATIONS INSTRUMENTS All Dranetz HDPQ instruments can be connected to the following circuit types:  Single phase  Split Phase  3 Phase, Four Wire Wye  3 Phase Delta  3 Phase (Floating or Grounded) Delta ...
  • Page 6 Xplorer and Xplorer-400 having additional circuitry to also capture high speed transients. It is important to note that the Dranetz HDPQ goes well beyond the requirements of IEC 61000-4-30 and EN 50160. In addition, the Dranetz HDPQ family employs the methods used for voltage transients to trigger on current transients.
  • Page 7 200ms window without any gaps between waveform, and if the difference exceeds the user’s windows. Being Class A, the Dranetz HDPQ family fully limits, an event is recorded. In the picture below, the complies with these requirements.
  • Page 8 Power Quality, Demand and Energy analysis, and reporting software. Real-time Meters, Trends and Event Lists All parameters available in the Dranetz HDPQ can be metered in real-time, trended over time, and can have trigger conditions enabled to record details of changes in each parameter.
