The dielectric loss tester/tan delta measuring instrument is a new generation of fully automatic portable insulating oil dielectric loss and resistivity meter designed according to GB / 5654. It can measure oil dielectric loss and volume resistivity at the same time, and has the characteristics of simple operation and accurate and reliable test data.
1. The structure of the instrument is an oil collecting cup, heating, temperature control and pressure regulating functions.
2. This device has its own automatic cup calibration function. The capacitance and dielectric loss factor of the empty electrode cup are measured to determine the cleaning and assembly of the empty electrode cup. Calibration data is automatically saved to facilitate accurate calculation of relative permittivity and DC resistivity.
3. The instrument has over-voltage, over-current and temperature-limiting protection functions, and has perfect protection functions. When there is overvoltage, overcurrent, and high voltage short circuit, the instrument can quickly cut off the high voltage and issue a warning message. A warning message is issued when the temperature sensor fails or is not connected.
4. High-frequency induction heating electrode cup, uniform heating for a short time.
5. The instrument adopts large-screen color touch screen design, easy to operate.
6. Directly measure the temperature by placing the probe inside the measuring electrode cup.
7. Contains positive selection wave generator, digital voltage regulation produces standard 50Hz high power test power supply.
