Multifunctional Comprehensive Transformer Tester
Darui Electric recommends for you:
The Multifunctional Comprehensive Transformer Tester is specifically designed for relay protection professionals to test current transformer (CT) volt-ampere characteristics, ratio testing, and polarity discrimination. It can also be used for transformer polarity discrimination tests, making it a high-performance, cost-effective multifunctional test instrument.
Main Functions
This instrument can automatically test and calculate the CT ratio; it features a large-screen graphic LCD with a full Chinese menu interface; cursor prompts guide operation, real-time display of test data and curves, with automatic scaling of curve coordinates for clearer reading; it has a low-voltage output mode to improve measurement accuracy; it can also serve as a complete set transmission test for protection; comprehensive protection functions; electronic polarity discrimination with audible and visual indication of test results, making it convenient and intuitive.
Detailed Description
1. Automatic testing: Based on the set test parameters, it fully automatically tests the CT volt-ampere characteristic data and automatically plots the excitation characteristic curve; automatically tests and calculates the CT ratio.
2. Large-screen graphic LCD with full Chinese menu interface, cursor prompt operation, real-time display of test data and curves, with automatic scaling of curve coordinates for clearer reading.
3. Built-in micro printer for real-time printing of CT volt-ampere characteristic test reports, excitation characteristic curves, and CT ratio test reports.
4. Dual operation modes: The main unit uses high-grade membrane key operation, and also has convenient communication interfaces (RS232 or USB) for connection to a laptop for operation, making it more convenient to use.
5. Built-in super-large capacity memory, capable of storing 6400 sets of test data; can be uploaded to a PC, and using the random software developed by our company, typical test reports can be automatically generated and edited, facilitating technical management and archiving. 6. Flexible configuration: The built-in voltage booster can raise voltage to 1000V, and with an external booster, it can be raised to 2000V; the current booster is external, and different capacities of current boosters can be selected, with a maximum output current of up to 1500A, meeting the test requirements of more CTs.
7. Low-voltage output mode: In the field, there are a considerable number of current transformers with relatively low test voltages. When performing volt-ampere characteristic tests, using the low-voltage output mode (maximum 300V) can significantly improve voltage regulation fineness and measurement accuracy.
8. Can also serve as a complete set transmission test for protection: Utilizing the advantage of the external current booster's large current output, it is very convenient and practical to perform complete set transmission tests on protection.
9. Electronic polarity discrimination with audible and visual indication of test results, making it convenient and intuitive.
10. Comprehensive protection functions: This instrument has overcurrent and overvoltage protection functions under microcontroller control, and can automatically adjust the overcurrent and overvoltage protection values based on the set test parameters to ensure the safety of the equipment under test.
