Performance Features
1. It can measure parameters such as transition waveform, transition time, transition resistance, and three-phase synchronization.
2. Dot-matrix LCD screen with hierarchical Chinese menu for simple and quick operation.
3. Intelligent testing and result analysis, with the ability to zoom in or out on waveform test results.
4. Three independent stabilized voltage sources are suitable for measurements without windings, and three independent constant current sources are suitable for measurements with or without windings.
5. Six independent signal processing channels with high-speed A/D conversion and 10KHz high-speed sampling to reflect parameter changes.
6. Built-in non-volatile memory can store three sets of waveforms and data for archiving, review, and analysis.
7. Comes with a perpetual calendar, displaying date and time, and can automatically print.
8. The instrument is equipped with a high-speed printer to print test results.
Precautions
1. Read the instructions carefully before using the instrument.
2. The operator should have general knowledge of electrical equipment or instruments.
3. It can work normally within an ambient temperature of -5°C to 40°C and relative humidity ≤80%, but when used outdoors, avoid rain and direct sunlight on the LCD screen.
4. Turn on the power switch only after all leads are connected.
5. After testing, wait for the discharge to complete before removing the test leads.
6. Do not move the test clips during the test.
7. If the current is too small, connect two or more wires in parallel as one measurement channel, and short-circuit unused wires with the black wire.
8. The power socket has a protective ground wire; please insert the plug into a three-hole outlet with ground.
Product Introduction:
Automatic Transformer Tap Changer Testeris a comprehensive measuring instrument used to measure and analyze the electrical performance indicators of on-load tap changers in power transformers and special transformers in power systems, according to the principles of the "Regulations for Handover and Preventive Tests of Power Equipment" and relevant regulations. It uses computer control and a specially designed measurement circuit to measure parameters such as transition time, transition waveform, transition resistance, and three-phase synchronization of on-load tap changers. With a brand-new testing principle and microcomputer technology, it allows testing the performance of on-load tap changers of various power transformers without disassembling or lifting the switch on site, displaying and printing transition waveforms and parameters. According to needs and site conditions, measurements can be taken directly from the tap changer leads, or directly from the transformer's three-phase bushings and neutral point.
