Power analyser and transient recorder in one device

Electrical Power & Protection
Magnet’s new A.Eberle high-performance PQ Box 150 is a network power analyser, meter and transient recorder in one device. “This compact new instrument has advanced features for reliability and easy operation,” explains Brian Howarth, managing director of Magnet. “It has an expandable memory and a sampling frequency of 20 kHz, double that of the previous series.
The PQ Box 150 has been developed for mobile operation and is suitable for measurements in public networks up to 600 V CAT IV, as well as for measurements in industrial environments up to 1000 V CAT IV. The power analyser measures the voltage quality accordingly against stringent requirements for low, medium and high voltage networks. Various triggering options enable quick location of the fault.
This shockproof device has an IP65 index protection rating to guard against the ingress of dust and water and is equipped with a robust power supply unit and application specific settings, which are easy to program.
A clear display provides information about the correct connection of measuring cables and current clamps and indicates on-line data of voltage, current, THD and power. The number of events that have occurred during operation and the recorded measurement duration are also displayed for the user.
The PQ-Box 150 detects the connected current-clamp set via a coding in the plug and automatically sets the correct measurement ranges. The device does not need to be informed of the transformer mounting ratio.
Multiple sessions can be recorded consecutively, without having to transfer data to a PC at the end of each recording. A manual trigger button enables recording of the current network status of a system in the form of an oscilloscope trace and 10 ms r.m.s values. Two additional buttons can be used to scroll the display and to adjust the settings of the device, for example, transformers in the medium and high voltage networks.
A USB 2.0 interface and TCP/IP is available to transfer the data. This instrument has a large 4 GB micro SD card memory and a slot for an SD memory card 1 GB to 32 GB. Evaluation software, which offers numerous evaluation options such as load analysis, trouble shooting in the network and automatic EN 50160 reports, can be installed on an unlimited number of PCs.
Various accessories, which enhance performance of these devices, are also available from Magnet. The company supports the A.Eberle range with a technical advisory and maintenance service throughout the country.
