Ohmmeter cuts the cost of low resistance testing
For the wide range of low-resistance testing applications, which require test currents of up to 200A, a digital low-resistance ohmmeter is a convenient and cost-effective choice.
Loop tester option avoids tripping RCDs
A test option which is guaranteed not to trip RCDs, and safe operation even if accidentally connected to a live three-phase supply, are among the key benefits of earth-impedance loop testers.
Software cuts the cost of test documentation
Two software packages offer electrical contractors an easy and inexpensive way of storing tests results, producing test reports, and generating certificates.
Topics covered by the guide, which makes extensive use of diagrams, tables and charts, include the need for low-resistance testing, how to interpret test results, and examples of the types of problems which can be revealed by testing.
Specific information is given on the value of low-resistance testing in several application areas, such as automotive assembly, power generation and distribution, aircraft assembly, and testing of circuit breakers, motors and transformers.
Also featured in the guide are sections discussing how commercial low-resistance ohmmeters operate, and explaining the techniques of resistance measurement, with a clear explanation of the differences and relative merits of two-, three- and four-wire testing.
Essential information is also given on the types of testers currently available, and how to choose between them.
The principle sections of Megger's guide to low-resistance testing are complemented by an extensive collection of appendices.
These provide additional information on related topics, such as calibration, sources of error in measurements, the effect of temperature and humidity on test results, and the choice of test modes.
Indispensible to all who are involved in carrying out low-resistance testing, or in specifying tests and interpreting results. Request a free brochure from Megger ...
