dielectric loss tester

Product Introduction:

The dielectric loss tester is a precision instrument designed to measure the energy loss generated by dielectric materials under the influence of an electric field. This loss is typically manifested as a phase difference between the internal current and voltage within the dielectric, known as the dielectric loss angle. The tangent value of this angle (tanδ) serves as a critical parameter in quantifying the magnitude of dielectric loss. By accurately measuring this parameter, the tester assists users in understanding the insulating properties of dielectric materials, thereby enabling the assessment of the operational status and safety of electrical equipment.

 

The dielectric loss tester typically consists of several key components: a high-voltage power supply, a test bridge, a standard capacitor, a signal processing unit, and a display unit. The high-voltage power supply is responsible for providing the necessary high-voltage electric field for testing, while the test bridge measures the dielectric loss angle. The standard capacitor serves as a reference to ensure the accuracy of the measurements. The signal processing unit amplifies, filters, and digitizes the measured signals for subsequent analysis and calculation. Finally, the display unit presents the measurement results to the user in numerical or graphical formats.

Large Screen Display: The tester features a large-screen menu-based operation with a brand-new Chinese interface, making the operation more intuitive and convenient.

Multiple Protection Mechanisms: The tester incorporates multiple protective functions that can quickly disconnect high voltage under conditions such as high-voltage shorts, breakdown, overvoltage, overcurrent, and voltage fluctuations, ensuring the safety of the testing process.

Massive Storage and Data Processing: Equipped with a calendar chip and a large-capacity memory, the tester can save historical records and export data via a USB drive for generating work reports on a computer.

Variety of Testing Modes: The tester supports multiple testing methods, including internal high voltage, external high voltage, internal norm, external norm, positive connection, negative connection, and self-excitation, catering to different testing needs.

 

Application Fields:

In the power industry, the dielectric loss tester serves as a crucial tool for assessing the insulating performance of electrical equipment. It is widely used for measuring dielectric loss in transformers, mutual inductors, bushings, capacitors, arresters, and other devices. By testing the degree of insulating media loss, it can effectively prevent various faults in electrical equipment caused by insufficient insulating performance. Additionally, this testing method can effectively detect overall moisture degradation and local defects in the insulation of electrical equipment, providing powerful support for preventive maintenance and fault diagnosis of power equipment.

 

Moreover, the dielectric loss tester also finds applications in the medical field. For instance, in detecting the biocompatibility of human tissues and diagnosing diseases, the tester can accurately measure the dielectric loss characteristics of human tissues, providing valuable data for medical research.

 

Overall, the dielectric loss tester plays a significant role in multiple fields such as power and medicine, providing effective technical support for equipment insulation testing, fault diagnosis, and medical research.
