The structure characteristics and measuring steps of transformer capacity and loss tester

Transformer capacity and loss measuring instrument has small volume, light weight, high measurement accuracy, good stability and other features, also USES the large screen LCD display window, menu action figure form with Chinese characters suggest that set many parameters in a screen display interface, the man-machine dialogue friendly interface, easy operation, and the advantages of easy to learn, greatly improving the work efficiency, It is the product of various power users and quality supervision departments.

Transformer capacity tester is composed of two parts, the host is the core of the instrument, all the electrical parts are inside the host, the host box adopts high strength imported waterproof injection molding case, durable, accessories box is used to place test wires and tools. Before testing, make sure that the parameters set are correct.

The test wiring of transformer capacity and loss tester must be carried out under the condition of grounding of the tested line to prevent electric shock by induced voltage. All short circuits, grounding and leads shall have sufficient cross sections and shall be securely connected. The test organization should be strict and the communication should be smooth to ensure the smooth progress of the test work. Use an electrical outlet with a ground cable.

During the short circuit test, if the high voltage or medium voltage side outlet bushing is equipped with annular current transformer, the secondary current transformer must be short-circuited before the test. During the short circuit test, the short connection of the non-pressurized side must be good, otherwise it will affect the test result. Cannot operate under voltage and current overlimits. Do not touch the metal part of the test line during the measurement to avoid being injured. Measuring wiring must be operated strictly according to the instructions, otherwise the consequences shall be borne by you.
