Background of the Art In recent years, with the great power construction, more and more new power system 15 devices are emerging, the impact of test results of high voltage test equipment is expanded, and the quality of data results is drawing more and more attention from the power production departments. Currently, there are many types of power transmission and transformation state maintenance test equipment used in power production, wherein they are of different quality. In this case, in order to control the quality of such test equipment, the provincial electric power 20 research institutes and departments are developing in an orderly manner the cycle measurement of power transmission and transformation state maintenance test equipment. According to the actual situation, the measurement and verification of power transmission and transformation state maintenance test equipment is mainly implemented by provincial electric power research institutes and departments. The standard measurement tools are mainly placed in fixed laboratory 25 environment. The specific work in done by periodical submission of the users to superior departments on by one, which has some drawbacks, mainly reflected in that: there are many grassroots users (such as power supply bureaus, power plants, etc.) and are dispersed, inspection equipment and transportation takes up much time. Meanwhile, superior metrology department fails to inspect in time due to too many equipment to be inspected so as to affect normal use of 30 the users. Some power transmission and transformation state maintenance test equipment is featured in large volume, large number or inconvenient submission. hmmA0129731509-vl 120457061 - 2 - With the deepening of smart grid construction, more and more smart substations and state maintenance test equipment are put into the power grid. As most state maintenance test equipment adopts the network operation mode. The equipment is installed directly in the grid and is difficult to dismantle. The traditional periodic submission to the laboratory for testing can 5 not be applied to state maintenance test equipment. Outage time for maintenance is limited so that long cycle of traditional inspection can not meet the power grid requirements. There is great uncertainty in the process of transportation. Thus, the qualified equipment after laboratory inspection may also be damaged in transportation so as not to guarantee the test data accuracy, thereby causing great risk for the safe operation of the power system.
