(redirected from ROCOF)
Also found in: Dictionary, Thesaurus, Medical, Legal, Acronyms, Encyclopedia.


the extent to which a product fulfils its function over a period of time.

The reliability of a product depends upon its design characteristics, the quality of materials and components embodied within it and the care with which it is made and assembled.

A product's reliability is an important part of its performance in use and thus affects the appeal of the product to customers and the likelihood of their buying it. See BRAND LOYALTY. See QUALITY CONTROL, FAILURE RATE CURVE, PARALLEL SYSTEM.

From this value, the ROCOF is calculated using a derivative filter of first order given by:
Step 12: Draw the ROCOF curve [ILLUSTRATION FOR FIGURES 5 AND 6 OMITTED] by plotting cumulative (usage) mileages [CM.sub.j] against the corresponding cumulative number of failures [CF.sub.j] for every j [element of] {1, 2, ..., k, k + 1}, the last time point (k + 1) being the end date.
So the rate of change of frequency (ROCOF) is also a commonly employed anti-islanding protection [13].
The quantity expressing failures per unit time is termed the failure rate, and has alternatively been defined by Ascher and Feingold[2] as the rate of occurrence of failures (ROCOF).
