The ED3000 series of Frequency-Independent Transformer Comprehensive Test Instruments is a professional testing equipment designed for the power industry, featuring notable characteristics and advantages. The following is a detailed analysis of its specifications:
Advanced testing principles
Variable Frequency Test: Utilizing the variable frequency test principle, comprehensive testing of CTs (Current Transformers) and PTs (Potential Transformers) can be achieved without the need for additional devices such as voltage regulators, boosters, and current amplifiers.
Low output voltage: The 180V AC output voltage and 12 Arms (36A peak) AC current ensure the safety of the testing process.
2. Comprehensive in features
Comprehensive Testing: Meets the testing requirements for excitation characteristics, transformation ratios, secondary winding resistances, secondary loads, phase differences, and angle differences for various CTs and PTs.
Accurate Measurement: Allows ±0.1% deviation error, ±5 minutes angular error, capable of on-site testing for 0.2S class current transformers.
Efficient Operation: Tests are simple and convenient, with one-click completion of multiple tests, and most test items use the same wiring method, significantly reducing workload.
High level of intelligence and automation
Automated Test Standard Selection: Capable of automatically selecting test standards based on transformer type and grade, such as GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207, etc.
Dynamic Graphic Interface: Full Chinese dynamic graphic interface, allowing for easy wiring and parameter settings without the need for a manual. It dynamically displays wiring diagrams, making operations more intuitive.
Data Storage and Printing: The device can store up to 1,000 sets of test data without loss upon power failure, and it comes with an onboard printer that can automatically print generated test reports.
4. Portable and Durable
Portability: The device weighs less than 9kg, making it easy to carry and suitable for on-site testing.
Durability: Utilizing high-performance DSP and FPGA, along with advanced manufacturing processes, ensures stable and reliable product performance, with a long lifespan.
5. Easy to operate
The Rotating Optical Mouse: Featuring a simple and quick operation with a rotating optical mouse, it's easy to master.
The LCD screen features a 5.7-inch graphic transreflective LCD, ensuring clear visibility even in sunlight, guaranteeing normal operation under any environmental conditions.
6. High Security
Low Output Voltage: The low output voltage ensures the safety of the testing process, guaranteeing the safety of both the tested equipment and personnel, even in the event of incorrect operation.
Parameters automatically provided: including breakpoint voltage/current, 10%(5%) error curves, accuracy limit factor (ALF), and instrument safety factor (FS), enhancing test accuracy and safety.
The ED3000 series Transformer Test Set is a comprehensive, highly intelligent, easy-to-operate, and reliable transformer testing instrument, serving as an ideal choice for transformer testing in the power industry.
