1. Features of LYYB-3000 Arrester Capacitive Current Tester
1) This device is a handheld operating instrument with a large Chinese display, easy operation, and reliable data testing.
2) Weighing only 0.5kg, it is significantly lighter than other similar instruments while offering more powerful functions.
3) It simultaneously tests the total current, resistive current, deflection angle, active power, capacitive current, and 3rd, 5th, 7th harmonic currents of three-phase arresters. It can also directly evaluate the performance of the arrester (excellent, good, fair, poor).
4) This instrument can use electric field induction or wireless transmission methods instead of PT secondary wiring.
5) This instrument can directly measure resistive current without connecting to PT secondary.
6) This instrument has multiple testing methods for convenience (PT, wireless, induction, no PT).
7) This instrument can test three phases simultaneously with automatic compensation, making it very convenient to use.
8) The instrument is equipped with a large-capacity 8000mAh lithium battery, allowing continuous operation for 36 hours on a single charge.
9) High-precision sampling and processing circuits, along with advanced Fourier harmonic analysis technology, ensure more reliable data.
10) The LYYB-3000 Arrester Capacitive Current Tester uses a unique high-speed magnetic isolation digital sensor to directly collect input voltage and current signals.
The specific operation instructions for the main menu of the Arrester Capacitive Current Tester are as follows:
l Phase: Press the "Function" key to move the cursor to "Single Phase", then press the Increase or Decrease key to select "Single Phase" or "Three Phase".
l Mode: Press the "Function" key to move the cursor to "PT", then press the Increase or Decrease key to select "PT", "No PT",
"Induction", or "Wireless".
l Compensation Angle: Press the "Function" key to move the cursor to "0.0", then press the Increase or Decrease key to modify the compensation angle.
Press the Enter key to change the increment/decrement rate (angle compensation is not recommended).
l PT Ratio: Press the "Function" key to move the cursor to "1.0", then press the Increase or Decrease key to modify the PT ratio.
Press the Enter key to change the increment/decrement rate.
l Start Measurement: Press the "Function" key to move the cursor to "Start", then press the Enter key to start measurement.
l View Data: Press the "Function" key to move the cursor to "Start", then press "Decrease" to enter the selection sequence number;
Press the Increase, Decrease, or Function keys to select the data to view, then press the Enter key to display that set of data;
When starting measurement, the following test interface will be displayed
