Application of DC Resistance Tester in practical operation

DC resistance test is an indispensable test item after the transformer is handed over, overhauled and the tap changer is changed. Therefore, it is very important to use a DC resistance tester to test the DC resistance of the transformer. Routine maintenance and good use of the DC resistance tester. The operation is very important for the normal operation of the DC resistance test. Therefore, it is necessary to solve the problems existing in the practical application and management of the DC resistance tester in a timely manner.

(1) The practical application of DC resistance tester and the imperfect management system

At present, many enterprises have not yet established a sound management system for instruments and equipment, or although they have formulated relevant management systems, they fail to strictly implement them in actual work, such as instrument and equipment procurement systems, loan and return systems, operating procedures, and maintenance systems, accident handling methods, etc. When purchasing equipment, the procedures of laws and regulations are not strictly followed, and the functions of the equipment do not match the actual needs, resulting in unnecessary waste of resources; there is no long-term planning for the purchase, and blind purchasing results in discontinuity of equipment; during the use of the equipment, there is no proper supervision of the equipment. Instruments and equipment undergo regular inspections and verifications, resulting in loss and loss of control of instruments and equipment. All in all, there are imperfections and unsatisfactory aspects in the planning, procurement, acceptance, management and other aspects of test equipment.

(2) Application of DC resistance tester in practice and management of accounts and physical objects

Irregular enterprises add large amounts and types of new instruments and equipment. Therefore, the accounts of instruments and equipment are miscellaneous and the registration work is arduous. Most of the accounts of enterprise test equipment are set up in the accounting department, and the accounting department pays more attention to the value calculation of the equipment and neglects to regularly check the quantity and value of the assets with the test equipment management department; the test equipment management department pays more attention to General work such as approval and acceptance of equipment, and daily management work such as regular inspection, verification and cancellation of equipment are ignored, resulting in incomplete equipment ledger establishment, inaccurate names, equipment not being labeled, misappropriating without permission, and not registering loans. and other phenomena, so that the accounting department and the test equipment management department will have discrepancies in the accounts at the end of the year.

(3) Partial aging of test instruments and equipment

As time goes by, some components of instruments and equipment will age and be damaged, equipment performance will decline, and energy consumption will increase. If these test equipment are not repaired or updated in time and continue to be used during the test process, it will be difficult to ensure the accuracy of the test data and seriously affect the quality of the test data results.

(4) The quality of test equipment management personnel is low

The knowledge structure of personnel engaged in the operation and management of instruments and equipment in many enterprises cannot adapt to the development requirements of modern experiments. For example, some large-scale precision instruments and equipment or imported equipment are updated quickly and have complex performance. Many test equipment personnel do not have relevant knowledge and skills, and do not have a good grasp of how to use the equipment. As a result, many experiments involving new knowledge and new technologies cannot be carried out normally, affecting the research and development of new technologies; in addition, laboratory managers lack equipment maintenance knowledge and fail to maintain the DC resistance tester in daily life or after testing, resulting in the instrument and equipment not being used normally, seriously affecting normal testing.
