Following the acquisition of
LEM Instruments, a division of
LEM Group,
Fluke has introduced the first
power quality analyser to offer IEC 61000-4-30 Class A compliance for accuracy up to 0.1% and synchronization to power frequency and GPS time registration. Test results can be acknowledged as evidence in contractual applications and legal disputes.
The tough LEM Topas 2000 is an enhanced version of the high-end LEM Topas. Developed in cooperation with power utilities providers, the Topas 2000 is optimised for field use in general industrial and power-critical applications such as electric utility distribution networks, hospitals and processing plants. It enables electrical engineers to conduct detailed analysis of power quality in medium and low-voltage networks, and assess power quality to EN 50160.
Can be optimised for each application:
The versatile measurement algorithms and trigger settings allow the expert user to optimise the Topas 2000 for each application to capture exactly the data required. With the GPS (DCF77) option, accuracy of time registration is better than 1µs. An accurate 'time stamp' is placed on all recorded events, enabling the source of a disturbance to be located by comparing recordings with time stamps taken at different locations. The Topas 2000 can analyse disturbances and their causes, assess reserves of transformers/feeders, carry out transient analysis, detect interference and power peaks, measure ripple control systems, and record day extreme values and load profiles. The eight-channel instrument can measure four currents and four voltages, or eight voltages. Powerful analysis software with a report writer is included.
Safety rated to Cat III 600 V:
The Topas 2000's precision data logger records measurement data for extended periods. Data can be transferred to a computer directly or through an integrated Ethernet network, even while the instrument continues to record. The instrument and its accessories and power supply are safety rated to Cat III 600 V, and conform to EN 61010-1.
Housed in an electrically insulated case, the rugged construction is built to IP50 for working in harsh environments. With a 1GB Compact Flash memory there are no rotating parts inside the instrument, increasing its reliability and durability over a temperature range from 0 °C to 50 °C. The Topas 2000 is available as a basic unit that can be expanded with various options and accessories as required.
In June 2005 the Fluke Corporation acquired LEM Instruments enhancing the Fluke product line by the addition of a comprehensive range of analysers and systems for power quality applications, earth/ground testers, insulation testers, low-resistance ohmmeters, clamp meters and clamp-on power meters.
