A new free publication offers comprehensive guidance on performing low-resistance measurements, which are essential to ensure the safe, reliable operation of many types of electrical installations.
A new free publication offers comprehensive guidance on performing low-resistance measurements, which are essential to ensure the safe, reliable operation of many types of electrical installations.
With nearly 50 pages of invaluable information and advice, Megger's "Guide to low-resistance testing" covers the subject in depth, providing all the practical guidance which contractors and engineers need to perform low-resistance tests, and to ensure that these tests yield dependable and accurate results.
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.
