Introduction

The design requirements of electrical measuring equipment are high reliability and long service life under normal operating conditions, and under unattended conditions Can work continuously without interruption. In order to effectively manage the measuring equipment, it is important to predict and estimate the life characteristics of different types of equipment by appropriate means. GB/T 17215.941 provides a method for predicting the failure rate of a metering device based on the component stress method (assuming it is a constant). GB/T 17215.9311 provides a method for estimating life characteristics by temperature and humidity acceleration reliability tests. GB/T 17215.931 The future may increase the reliability of other stress test. This part provides an important measure to assess the durability of the equipment - the test method for measuring the stability of the measurement properties, The product is operated for a longer period of time at the upper limit of the specified operating temperature, voltage and current operating range and tested during the test and after recovery Percentage change in the amount of error. GB/T 17215.932 The future may include additional assessment of other types of stress or durability. Electrical measurement equipment reliability Part 321. durability - metering characteristics at high temperatures Stability test

1 Scope

This part of GB/T 17215 specifies a test method for the stability of the metering characteristics of the energy meter, that is, the test sample is subjected to a specified temperature Degree, voltage and current operating range of the upper limit conditions for a long period of time, and test its test and recovery percentage after the error Change the amount. Performance characteristics other than the accuracy of the energy metering are not covered by this section. Note. This test can not give the energy meter work in normal conditions, the stability of its measurement characteristics can be maintained for a long time conclusion. This part applies to all types of energy meters within the scope of IEC /TC13.
