In their work, power workers often need to use a microcomputer relay protection tester. So what are the main functions of this device? And what are its uses? This article will provide a brief introduction.
The microcomputer relay protection tester is mainly used for performance testing of power relays and power transformers. It has many features such as high precision, high speed, convenience, and flexibility, and is widely welcomed by power workers.
The YTC1000 microcomputer relay protection tester is a new type of miniaturized relay protection tester that is based on the People's Republic of China electric power industry standard "Technical Conditions for Microcomputer-Based Test Equipment for Relay Protection" (DL/T 624 ─ 1997), extensively listens to user opinions, summarizes the advantages and disadvantages of similar domestic products, and fully utilizes modern microelectronic technology and components.
It can operate standalone or be connected to other computers. The host has a built-in high-performance industrial computer and high-speed digital signal processor, true 16-bit DAC module, new modular high-fidelity high-power amplifier, built-in TFT true color LCD display and embedded microcomputer keyboard.
The YTC1000 microcomputer relay protection tester can be operated standalone or connected to a laptop. It has powerful operation functions, small size, and high precision. This relay protection tester has both the superior performance and powerful functions of a large tester, and the advantages of a small tester such as compactness, flexibility, simple operation, and high reliability. It has a high performance-price ratio and is a handy tool for relay protection workers.
Product Features:
1. Flexible combination of voltage and current outputs: It can output up to 6 phases of voltage and 6 phases of current, and can be arbitrarily combined to achieve conventional 4-phase voltage and 3-phase current, 6-phase voltage, 6-phase current, and 12-phase output modes. It is compatible with various traditional test methods and can also conveniently conduct three-phase transformer differential tests, plant power fast switching, and standby power automatic switching tests.
2. Operation method: The device can be directly connected to an external laptop or desktop computer for operation, which is convenient, fast, and stable in performance.
3. New high-fidelity linear power amplifier: The output stage consistently uses a high-fidelity, high-reliability modular linear power amplifier, rather than a switching power amplifier, ensuring reliable performance. It does not cause high or medium frequency interference to the test site, and ensures smooth waveform and excellent accuracy from large currents to tiny currents.
4. High-performance host: The output part uses DSP control, with fast computing speed, strong real-time digital signal processing capability, wide transmission bandwidth, and high-resolution D/A conversion control. The output waveform has high precision, low distortion, and good linearity. A large number of new technologies and reliable components and materials are used, and professional structural design is adopted, so the device is small in size, light in weight, full in functions, easy to carry, and can work immediately after power-on, making mobile testing very convenient.
5. Powerful software functions: It can complete various large and complex calibration tasks with high automation, conveniently test and scan various protection settings, perform fault replay, store test data in real time, display vector diagrams, and print reports online. The 6-phase current can conveniently conduct three-phase differential protection tests.
6. Dedicated DC power supply output: It is equipped with a dedicated adjustable DC power supply output of 110V and 220V.
7. Complete interfaces: The device has a USB communication port and can communicate with computers and other external devices.
8. The six-phase microcomputer relay protection tester has comprehensive self-protection functions: The heat dissipation structure design is reasonable, hardware protection measures are reliable and complete, with power soft-start function, software self-diagnosis of faults, and output blocking functions.
