Data analysis system and method.
Background technology
At present, arrester is to ensure one of visual plant of safe operation of power system.Metal oxide arrester is powered
Tester is the technical way of lightning arrester live-line test, the change of leakage current can reflect the making moist of arrester, aging,
The defects such as loose contact, by measuring the leakage current of arrester under working voltage, typically can relatively be accurately judged to take shelter from the thunder
Device whether there is defect.General lightning arrester live-line test is carried out before and after annual thunderstorm season, it is necessary to measure the full electricity of arrester
Stream and current in resistance property, and compared with maiden trial and all previous test data, according to code, it is more than when arrester resistance current increases
At 1.5 times, then show that arrester produces failure, now need to have a power failure and further carry out other experiments, ascertain the reason.Arrester is surveyed
The change of impedance angle, the change of odd electric current in examination data can also reflect the change of arrester state to a certain extent.
In addition, the change of ambient temperature and humidity, the change of different time sections system loading, the fluctuation of system voltage in test process
