A suitable case for power analysis
Supplied in a compact, easily portable suitcase format, the PA-9 Plus power analyser provides comprehensive self-contained facilities for monitoring the quality of electrical supplies.
Supplied in a compact, easily portable suitcase format, the new PA-9 Plus power analyser from AVO International provides comprehensive self-contained facilities for monitoring the quality of electrical power, both in the laboratory, and in the most demanding on-site locations Self-powered from the unregulated supply under test - or, if more convenient, separately powered from an auxiliary input - the new instrument records all power quality and power flow parameters, including voltage, current, real power and reactive power, energy and demand interval data

Handheld testers star in catalogue
No fewer than 50 instruments, ranging from insulation and continuity testers to LCR test sets, are featured in the new handheld product catalogue from Megger.
Fibre-optic testing now easier to perform
Fast, comprehensive testing of fibre-optic installations is now easier to perform with the latest range of low-cost Megger fibre-optic light sources and power meters
Five input channels are provided for current, plus four differential channels for voltage.
The PA-9 Plus also provides real-time harmonic analysis from DC offsets up to the 63rd harmonic, and event- or time-triggered waveform capture.
Up to two pretrigger sequences can be captured, along with as many as 99 post-trigger sequences.

Savings in time and money can be made on locating faults in power cables - particularly if they are buried or otherwise inaccessible - by using the latest hand-held time-domain reflectometers
Ohmeters extend to inductive loads
AVO International has extended the capabilities of its popular Ducter DLRO10 and DLRO10X digital low-resistance ohmeters to include accurate resistance measurement for inductive loads.
All results are shown on the integral LCD screen.
A particularly important feature of the PA-9 Plus is its ability to indicate the direction of harmonic current flow.
This is a major aid to tracing the location of harmonic sources, such as variable speed drives and switch-mode power supplies, which may be the cause of supply pollution.
The instrument is capable of storing all of the data it captures for later analysis.
Recording modes offered include continuous and out-of-limits only, making it ideal for long-term monitoring of troublesome supplies.
Captured data may be analysed using the instrument's own facilities, or can be transferred to a PC via a serial link.
Data may also be copied to a standard plug-in PCMCIA memory card, which offers a convenient means of downloading the memory on site, and also of rapidly transferring large amounts of data to a PC.
The instrument can write to this memory between tests, dramatically increasing data storage capacity.
The memory card may also be used to transfer new configurations to the instrument, without the need for a computer connection.
The PA-9 Plus power analyser from AVO is complemented by the new Megger PA-9W software package for Windows, which is supplied free-of-charge with every instrument.
Designed to work specifically with the data from the PA-9 Plus, this powerful package provides enhanced analysis tools and a comprehensive range of printed reports in both graphical and tabular format.
Among the features offered by the software are trending of individual harmonics, total harmonic distortion (THD) and total demand distortion (TDD), along with data preview for charts, graphs, and reports prior to retrieval, as well as facilities for selectively obtaining only the data which is of specific interest.
