HZ-KG7 Vacuum Switch Vacuum Tester also used computer for synchronous control, data acquisition and processing, and the sensitivity of HZ-KG7 Vacuum Switch Vacuum Tester in the field test of the vacuum interrupter arc chamber is 10^-5Pa. The most prominent feature of this instrument (HZ-KG7 vacuum tester) is to use the new excitation coils and data processing methods to achieve the non-demolition measurement of vacuum. The instrument is practical, easy to use, easy to operate, high precision measurement without disassembly, widely used in electric power, steel, petrochemical, textile, coal, railways, and other trades using the vacuum switch.

HZ-E-I high-voltage bridge locator is based on the MURRAY bridge principle. It is used for positioning a variety of wire and cable breakdown point or no breakdown but low insulation resistance value defect point, and high-voltage cable protection sheath faults. It can also be used for cable factory to test cable defects.

The device using SMPS to form high-voltage constant current source, no-load voltage is -15000V, short-circuit current is 30mA. Using a high sensitivity amplifier and galvanometer to indicate the balance, with the proportional potentiometer to form a balanced bridge and placed at high potential. Test line is the specially designed dual-core high-pressure rubber cable, use four-terminal resistance measurement to avoid the error arising from lead resistance, the test line is reliable grounding through braid shield, the panel operation button at the earth potential, operate the bridge through insulation bar. High voltage constant current sources and bridges are integrated in a portable industrial chassis. Therefore, the device voltage is high, light in weight, easy to operate and safe to use.

In power transformers used in the production of semi-finished and finished products, before a new transformer is put into operation, and according to the national ministry’s preventive testing procedures, the transformer’s turn ratio (or voltage ratio) test must be conducted. This test checks the correctness of the transformer’s turn ratio, the condition of the tap changer, whether there is a turn-to-turn short circuit, and whether the transformer is capable of operating in parallel.

The HZBB-10B transformer turns ratio meter intelligent transformer ratio group test, using a new algorithm developed by our company, can measure the three-phase transformer ratio without requiring adjustment of the three-phase power supply balance, ensuring accurate measurements. As a result, the test is fast and can measure the ratio and wiring configuration in approximately 3 seconds.

In the production of power transformers, both semi-finished and finished products undergo testing. Before a new transformer is put into operation, the national preventive testing procedures require a transformer turn ratio or voltage ratio test. This test checks the correctness of the transformer's turn ratio, the condition of the tap changer, the presence of any turn-to-turn short circuits, and whether the transformer can operate properly.

Traditional variable ratio bridge readings are not intuitive, as they require conversion and can only be measured phase by phase. The XXF variable ratio tester overcomes the limitations of traditional variable ratio bridge testing by offering a simple and intuitive operation. It uses a three-phase precision inverter power supply for fast testing with high accuracy.

A Transformer Turns Ratio (TTR) tester is a specialized instrument used to measure the turns ratio of transformers, which is essential for ensuring their proper functionality and reliability. The turns ratio is the relationship between the number of turns in the primary winding and the number of turns in the secondary winding of a transformer. Accurate measurement of this ratio is crucial for assessing transformer performance, diagnosing faults, and ensuring compliance with industry standards.

TTR testers are crucial for measuring the turns ratio of transformers, ensuring their reliability and performance. Huazheng Electric Manufacturing (Baoding) Co., Ltd. has developed advanced TTR testers,which offers precise measurements, user-friendly interfaces, and protective features. The device can perform simultaneous three-phase tests, enhancing efficiency and accuracy. With a focus on quality and innovation, Huazheng Electric is a leading manufacturer in the electrical testing industry, providing essential tools for maintaining reliable electrical infrastructure.
