application

Fundamentally solving the problem of accurate measurement under strong electric field interference. It is also applicable to situations where a generator is used for power supply testing after a complete power outage. This instrument is equipped with an insulating oil cup to test the dielectric loss of insulating oil.

Notes:

1. The instrument must be used in an environment equipped with a standard ground wire.

2. Regularly fill the oil cup with clean and dry oil to protect it.

3. Regularly wipe the surface of the electrode with soft fur or silk cloth to maintain a smooth finish.

4. Proper use and protection are required, and users generally have no faults that can be repaired. The chassis should not be opened at will. If it does not work properly, please contact our company in a timely manner

feature

Large LCD Chinese display

The instrument is equipped with a large screen (105mm × 65mm) Chinese menu interface, which is divided into left and right parts. The left side is the functional menu area, and the right side is the relevant status information prompt. Each step is very clear, and operators do not need professional training to use it. One operation, the microcomputer automatically completes the measurement of the entire process, which is currently an ideal dielectric loss measurement device.

Massive storage of data

The instrument is equipped with a calendar chip and a large capacity memory, which can save the test results in chronological order, view the historical records at any time, and print and output them;

Scientific and advanced data management

The instrument data can be exported through a USB flash drive, and can be viewed and managed on any PC through our company's software to generate work reports.

Multiple testing modes

The instrument can be tested using various methods such as internal high voltage, external high voltage, internal standard, external standard, positive connection method, reverse connection method, self-excited method, etc; Under high voltage conditions outside the standard, high voltage (greater than 10kV) dielectric loss can be achieved.

CVT testing in one step

This instrument can also test the dielectric loss and capacitance of fully sealed CVT (capacitive voltage transformer) C1 and C2, achieving simultaneous testing of C1 and C2. This instrument can also test the CVT ratio and voltage angle difference.

Measuring CVT without dismantling the high-voltage lead wire

The instrument can accurately measure the dielectric loss and capacitance values of the CVT without removing the high voltage leads of the CVT.
