What is PD IEC TR 62059-11 - Dependability of static electricity metering equipment about?
When it comes to electricity supply systems, performance and reliability of electricity metering equipment is essential for fair and accurate meter readings.
PD IEC TR 62059 is a standard that discusses electricity metering equipment. PD IEC TR 62059-11 is the 11th part of the series that covers general aspects of the dependability of static metering equipment for electrical energy measurement and load control. It contains information on the role in dependability management of the various parties involved and, on the methods, applicable during the whole life cycle.
Who is PD IEC TR 62059-11 - Dependability of static electricity metering equipment for?
PD IEC TR 62059-11 on dependability of statis metering equipment is relevant to:
- Static meter manufacturersand purchasers
- Anyone involved in design, installation, maintenance and commissioning of static meters
- Power distribution and transmission companies
- Local authorities
- Inspection authorities
- Regulatory bodies
- Engineers
Why should you use PD IEC TR 62059-11 - Dependability of static electricity metering equipment?
The present worldwide transition from electromechanical to static electricity metering equipment requires the application of the most recent results of reliability research to this new metering technology. This is of particular importance as metering equipment is expected to be in use for long unattended periods. The experience from more than a century of developing and manufacturing electromechanical meters is not entirely applicable to static meters, since both designs exhibit different failure modes.
It is for this reason that a working group was created to investigate the applicability of presently available standards to the dependability of static electricity metering equipment. A further reason for this decision was that the procedures applied during type approval and acceptance inspection are not adequate to determine the reliability of static electricity metering equipment during the products life cycles from specification and design to decommissioning.
The work program includes dependability management through data collection and analysis of field failure data, reliability testing, failure rate prediction and software aspects of dependability.
PD IEC TR 62059-11 deals with all types of static metering equipment for electrical energy measurement and load control. Therefore, it is necessary to describe and define the main elements of the metering system life cycles and the role of all parties involved. It is thus assumed that the meters are:
- Designed, manufactured and tested
- Subjected to type test, approval and initial verification, if required
- Monitored during their useful life to verify that they are installed, measuring and functioning correctly
- Removed and replaced as soon as they are found to be faulty
