Power Quality Analysers & Metering

Many products in this range offer features of both power measurement and power quality analysis. The decision to use which should be based upon the primary need - power quality analysis or revenue/check metering. Portability, fixed installation and the need for local display or SCADA connection should be considered. The staff at HV Power will be pleased to discuss your application and give guidance.

PQ-Box 50

PQ Box 50

The PQ-Box 50 is a powerful, portable and very easy to use Power Quality Analyser for a wide range of industrial and utility applications. Due to its integrated power supply, robustness and compact design, the power analyser is particularly suitable for mobile measurement operation (IP65) in harsh environments. This entry into the A.Eberle PQ-Box range does not feature local display, but PC or phone app.

PQ-Box 100

PQ Box 100

The PQ-Box 100 is the work horse multi-function portable instrument for power, energy and power quality analysis. This robust solid state design is designed for outdoor use, yet boasts 24 bit resolution, 0.1% accuracy and over 1600 measured parameters for advanced engineering analysis. Very simple set up and on screen confirmation of measured values ensures correct connection.

The PQ-Box 100 is supplied with PC software which not only extracts and process pre-recorded data, but also acts as a live recording oscilloscope and harmonic analyser. High speed USB connection permits rapid download of data.

PQ-Box 150

PQ Box 150

The PQ-Box 150 essentially sits between the ‘work horse’ PQ-Box 100 and ‘thoroughbred’ PQ-Box 200 products. For some customers the PQ-Box 100 will remain the product of choice, while for others the PQ-Box 150 is the logical upgrade. The good news is that all products are supported by the same version of WinPQ mobil software – so you can operate a mix of products within your organisation.

Compared to the PQ-Box 100, the PQ-Box 150 features colour on screen graphics and faster sampling speed to allow up to the 200th harmonic to be measured. The unit is CAT III 1000V rated, with built-in fused leads. The six-hour internal battery and extremely tough external power supply boasts a very wide input range and very high impulse withstand. A.Eberle have moved to this design to cater for a ‘worst case scenario’ situation. Should the power supply be damaged – such as from a rogue frequency drive output – the power supply can simply be replaced, without risk to the PQ-Box 150. A.Eberle’s testing of this robust power supply included such abuse as running from a 40 Vac source in a 70 deg. C environment and, running it from a 550 Vac source!

PQ-Box 200

PQ Box 200

The PQ-Box 200 is an expansion of the PQ-Box 100 & PQ-Box 150 for those needing high speed transient data capture. It features an additional A/D card with +/- 5 kV and 2 MHZ tansient capture capability. The PQ-Box 200 also features both an Ethernet and USB interface, a binary trigger input and low voltage analogue input channel.

All the PQ-Box products share the same setting and reporting software “WinPQ mobil”, allowing users to operate a mix of tools with little additional support.

PQ-Box 300

PQ Box 300

The PQ-Box 300 is an expansion of the PQ-Box 200 with additional high speed measurement to allow harmonics of up to 170 kHz to be measured.

All the PQ-Box products share the same setting and reporting software “WinPQ mobil”, allowing users to operate a mix of tools with little additional support.

PQI-D, PQI-DA, and PQI-DA Smart power quality analysers

The PQI-D series of power quality analysers are designed for permanent installation and continuous monitoring of power quality in medium and high voltage networks. Features include voltage quality to EN 50160, high speed fault recorder, event recorder, harmonic analysis and ability to monitor additional I/O points.

The PQI-D is a modular design with rack and enclosure mounting options. The PQI-DA features a non expandable stainless steel DIN mount enclosure. The PQI-DA Smart is the latest release to the family and features a moulded DIN rail mount, with integral LCD display. The PQI-DA Smart features removable SD memory card, ideal for locations where communication infrastructure does not yet exist. The PQI-D Smart also features expanded measurement capability in the 2 kHz to 9 kHz frequency band.

Data is downloaded to PC running WinPQ software for display and analysis of data. WinPQ supports the connection of multiple recorders distributed geographically within a network using a variety of communication methods.

Shark 200

Shark 200

The Shark 200 is a panel mount data-logging revenue meter with plugin I/O modules. Power and energy readings are logged in internal memory together with time stamped limit/alarm events. With the installation of mA output cards, the Shark 200 can be used as a transducer to output measured or calculated values to legacy systems. Digital I/O cards can be used for logging of external events or as control outputs. DNP3.0 and Modbus protocols via RS-485 are supported for quick connection to SCADA, with fibre serial output also possible. Multiple Ethernet ports are available for advanced communications with IEC 61850 or DNP-iP. MV-90 is supported and built-in web pages provided.
