Introduction

Currently in the world, the use of electrical measuring equipment from electromechanical to static transition, in this new measurement technology is required to make Reliability with the latest research results. When it is desired measuring equipment unattended in the long run the state, the reliability is especially important.

More than a century of experience in the development and manufacture of electromechanical meters and still not be fully applicable to the instrument, because it presents a two designs Different failure modes.

It is for this reason, the National Electrical Instrument Standardization Technical Committee has set up a working group to study currently available the applicability of the standard static electrical measurement equipment credibility. A more important reason for this decision is that the current type of identification and verification Income verification test procedure does not apply to static electric measuring device to determine the performance indicators, designed to stop the use of the entire life cycle reliability.

The work plan includes the credibility of the management of field failure data collection and analysis, reliability testing, and failure rate prediction software Credibility problems.

Any device's credibility depends on many factors, such as its functionality, complexity, design, manufacturing process, failure criteria, working conditions, so with time, installation and maintenance procedures. Some of these factors are controlled by the manufacturer, while others are equipment operators and users responsibility any. For this reason, there is no specific definition of reliability and availability requirements, these requirements should be left between the involved parties Consultations.
