Industry personnel must first go through the replacement and repair of damaged, damaged, deformed, rusted, abraded, fractured, loose, leaking, and other parts of the components, and restore them according to the original procedure. Pay attention to the front and back and the up and down directions. , The installation accuracy should be ensured within the tolerance scale. If the automatic ratio tester is required to be in a horizontal state (zero position), it cannot be omitted. If the lubricant is used, pay attention to the type of lubricant used and the order of filling. .

Secondly, after analyzing and judging the situation of the transformer ratio tester, if there is a problem, it can be disassembled, and the installation and connection of various parts must be carefully observed before proceeding; the installation accuracy and disassembly procedure are for the troublesome parts The disassembly should be recorded to prevent mistakes during the recovery. Do not forcibly disassemble the parts that are not easy to disassemble. Instead, use rubber, plastic or wooden hammers and tap them lightly to loosen them before disassembling.

Parts of different materials such as metal, rubber, glass, magnetics, etc. should be stored separately, and at the same time, avoid losing them, especially if they are magnetized, they will affect the use. Never dismantle the parts that are not necessary to dismantle. If you are not sure of solving the problem, please ask professional machinery to repair it.

Then, the pointer deformation, the scale ruler wear, the paint peeling off, the blurring, the display electrical signal interruption or the electrical parameter abnormality that affect the normal display and accurate reading should be replaced.

After the correction, installation and commissioning are completed, no-load and actual-load test operation should be carried out. For those that directly affect the measurement readings, please mark: verification by the measurement department to ensure the data and instrument performance parameters detected by the ratio tester All meet the requirements. Judgment should be made on the operation and application conditions, and records should be kept on file.
