The phenomenon of hidden malfunction and its detecting method applied to diesel engine and supplementary system of the series of DF 4 locomotive are introduced.

Discussion on Potential Risks of Campus Network and Their Solutions

Analytic method for relay protection importance with consideration of hidden failures;

The basic process and theory of power system cascading failure considering protection system hidden failures were analyzed to decrease bulk blackout failure.

For the purpose of investigating how the failures spread in the power grids, finding out the key-lines affecting the cascading failures, this paper presents an approach to calculate the risk of line outage and identify key-lines causing blackouts based on the hidden failure model and risk theory.

It will possibly be a lethal mistake if using the defective mathematical model in terms of RCM Ⅱ(reliability-centered maintenance Ⅱ) to calculate the rate of hidden faults especially those hidden faults concerning safety and environmental adversity.

Compared with the tradition maintain theories,it put forward the concealment of hidden fault,analyzing the close relation between hidden faults and heavy breakdowns.
