in the EPOT-III ?

General Information:
In power systems, railway systems and large petrochemical factories and mines, enterprises have a large number of electrical equipment, and most of their internal insulation is oil-filled insulation. The dielectric strength of insulating oil is a routine test that must be measured. In order to meet the needs of the market, our company has independently developed and produced a series of insulating oil dielectric strength testers according to the national standard GB/T507-2002, the industry standard DL429.9-91 and the power industry standard DL/T846.7-2004. This instrument takes a single-chip microcomputer as the core, realizes all the automation of the test, high measurement accuracy, improves the work efficiency, and greatly reduces the labor intensity of the staff. At the same time, the instrument has a small appearance and is easy to carry.
EPOT conforms to international standard IEC-156.

Aslo called: Transformer Oil BDV Tester, Insulation Oil Measuring Kit, Insulating Oil Dielectric Withstand Voltage Tester, Insulation Oil Dielectric Strength Voltage Meter.

-The instrument uses a microprocessor to automatically complete operations such as boosting, maintaining, stirring, standing, calculating, and printing.

-Large-screen color LCD display, touchable, English menu and small size.

-The instrument is easy to operate, the operator only needs to make simple settings, and the instrument will automatically complete the pressure test of 1 cup of oil samples according to the settings. The breakdown voltage value and cycle times of 1 to 10 times will be automatically stored. After the test is completed, the thermal printer can print out the breakdown voltage value and average value of each time.

-Power-off retention, can store 100 experimental results.

-The single-chip control is used to boost the voltage at a constant speed, and the voltage and frequency are accurate to 50HZ, which makes the whole process easy to control.

-It has overvoltage, overcurrent, limit and other protections to ensure the safety of operators.
-With the function of displaying the measured temperature and system clock.

-Standard RS232 interface, can communicate with computer.

-USB interface, can export test data.
