Level 5 complete qualification anti-interference dielectric loss tester

Instructions for Use

3.1 Contrast Adjustment
The contrast of the LCD screen has been calibrated at the factory. If you feel that it is not clear enough, you can adjust it using the following methods:
Press and hold ↑ or ↓ without moving, then turn on the main power switch, and press ↑ or ↓ to adjust the display contrast. After adjustment, press the "OK" button to exit.
3.2 Enter Menu
After turning on the main power switch, the startup screen will first be displayed:

Then automatically enter the measurement menu.

3.3 Choose wiring method
The cursor is in the "forward" position, press ↑↓ to select the "forward", "reverse", and "CVT" measurement methods.

3.4 Selecting internal and external standard capacitors
The cursor is in ②, press ↑↓ to select "Internal Standard" and "External Standard", indicating the use of internal or external standard capacitors. Usually, internal standards can be used for positive and negative wiring measurement and CVT self-excited measurement. For high voltage dielectric loss, external standard methods are used, and external capacitance parameters need to be incorporated into the instrument. The cursor is on "Outer CN". Press and hold the "Start Stop" button for more than 1 second to display the outer standard capacitance value. Press the ↑↓ keys to modify this value. After modification, press and hold the "start stop" button for about 1 second. When you hear the buzzer sound, release the keyboard to save.

3.5 Selection of Test Frequency
3.5.1 Default startup frequency
The cursor is on "frequency conversion", indicating automatic frequency conversion at 45/55Hz. The instrument automatically measures once at 45Hz and once at 55Hz, and then calculates the data without interference at 50Hz. The default mode for automatic startup is this, it is recommended to use it.

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.
