HOPU HJS Series ISO-Certified Insulating Oil Tan-Delta & DC Resistivity Tester

This equipment integrates precise temperature control, high voltage AC & DC power supply and automatic measurement system. It can set adjustable AC test voltage, DC test voltage and sample temperature according to test standards. It supports sample testing and direct testing modes, widely used in power utilities, transformer factories, oil laboratories and third-party inspection institutions.

The tester comes with standard stainless steel test cells, connecting wires and complete accessories. It features touch screen operation, automatic data recording and stable repeatable test results, helping users evaluate the insulation performance and aging status of insulating oil efficiently.

Advantages

1. High automation, heating, measuring dielectric loss, and measuring resistivity can be completed at a time;

2. The three electrode type structure with an GB/T5654-2007 standard, inter electrode spacing

  2mm, can eliminate stray capacitance and leakage effect on the dielectric loss test results;

3. The instrument uses medium frequency induction heating, PID temperature control algorithm. This heating mode has the advantages of non-contact, oil cup and          heating body, uniform heating speed, convenient control. The temperature control in temperature within the preset range error;

4. DSP and FFT technology are used to ensure the stability, accuracy and reliability of the data;

5. Internal standard capacitor for the SF6 charging three pole capacitor, dielectric loss and capacitance of the capacitor is not affected by ambient temperature,                humidity, etc., so that the accuracy of the instrument after a long time to use is still guaranteed;

6. Large screen color touch screen, man-machine dialogue convenient, concise operation, clear;

7. With the lid off the high voltage, high voltage electrode cup short reminder, eliminate safety hazards, to ensure the normal operation of the safety of operating                personnel and equipment;

8. With a real-time clock, the test date and time can be saved, displayed, and printed with the test results; the equipment can display the ambient temperature and            detect the test environment in real time;

9. Automatically store measurement data, and can store 100 sets of measurement data;

10. Correction function of empty electrode cup. The capacitance and dielectric loss factor of the empty electrode cup are measured to judge the cleaning and                     assembling condition of the empty electrode cup. The calibration data are saved automatically to facilitate the accurate calculation of relative capacitance and DC         resistivity;

11. The instrument has an RS232 data serial port.
