Relay protection calibrator is a commonly used tool in power systems, mainly used for testing, verifying, and debugging various relay protection devices. This equipment plays an important role in the safe and stable operation of the power system, therefore it is very important in the construction and operation of the power system.
The function of the relay protection calibrator is very powerful. It can test and verify various types of relay protection devices, including overvoltage protection, undervoltage protection, overcurrent protection, grounding protection, etc. During the testing process, the calibrator will simulate various fault situations, so that testers can verify whether the relay protection device can effectively protect the power system.
When using a relay protection calibrator, the following points should be noted:
1. Ensure that the test parameters, including test voltage, current, etc., have been set correctly before testing.
2. Before testing, it is necessary to check whether the wiring of the relay protection device is correct to avoid inaccurate test results.
3. During the testing process, it is necessary to follow the operating instructions of the testing instrument to avoid testing failure or accidents.
4. During the testing process, it is necessary to ensure safety and avoid dangerous situations such as electric shock and short circuit.
5. After the testing is completed, it is necessary to analyze and record the test data for subsequent analysis and processing.
In short, relay protection calibrators play a crucial role in the power system, as they can effectively ensure the safe and stable operation of the power system. Therefore, when using the instrument, it is necessary to strictly follow the operating instructions and pay attention to safety to avoid accidents.
ZCAR-802 three-phase relay protection tester is a new type of miniaturized microcomputer relay protection tester, which is based on the "Technical Conditions for Microcomputer-based Relay Protection Test Devices (Discussion Draft)" issued by the Ministry of Electric Power, summarizes the advantages and disadvantages of similar domestic products, and fully utilizes modern advanced microelectronics technology and devices to achieve. The instrument operates independently on a single machine, with strong functionality, small size, and high accuracy. It not only has the superior performance and advanced functions of large testers, but also has the advantages of small and flexible testers, simple operation, high reliability, and high cost-effectiveness. It is a handy tool for relay protection workers. In addition to verifying various relays (such as current, voltage, inverse time, power direction, impedance, differential, low cycle, synchronization, frequency, DC, intermediate, time, etc.) and microcomputer protection, it can also simulate transient and conversion faults from single-phase to three-phase for whole group testing. It can also complete various large-scale and complex verification tasks with high degree of automation, automatically test and scan various protection settings, store test data in real-time, display vector maps, print reports online, and so on.
