Technical knowledge：EMC Laboratory Site Introduction: Electrical Fast Transient/Burst (EFT) Section
I. Test Items
The Electrical Fast Transient/Burstis mainly used to evaluate the immunity capability of electrical and electronic equipment when subjected to rapid transient pulse group interference. The test objects cover the power supply port, signal port, control port and grounding port of the equipment.
II. Test Objectives
This test aims to verify the equipment's resistance to transient disturbances caused by switching transient processes (such as switching inductive loads, relay contact bouncing, etc.), thereby enhancing the electromagnetic compatibility (EMC) of the equipment and ensuring its stable operation in complex electromagnetic environments.
III. Test Principle
The Electrical Fast Transient/Burstcouples a group of rapid transient pulse pulses to the power port, control port and grounding port of the equipment to simulate the actual electromagnetic interference scenario. This test has the characteristics of high transient amplitude, short rise time, high repetition frequency and low energy, and can effectively evaluate the immunity performance of the equipment.
IV. Equipment Capabilities
• Fast Noise Generator NSG 3040A: Complies with IEC 61000-4-4 Ed.3 standard, can simulate various electromagnetic interference effects, with the highest test voltage reaching 4.8 kV.
• Built-in Coupling/Damping Network: Supports single-phase EUT, voltage range 300 VAC/DC, maximum current 16 A.
• Three-phase Coupling/Damping Network: Supports 690 VAC / 1000 VDC, maximum current 100 A.
• Capacitive Coupling Clamp: Suitable for all signal and control ports for testing, ensuring comprehensive coverage of the test.
V. Technical Advantages and Customer Value
• Precise and Efficient: Relying on advanced waveguide anechoic chambers and test equipment, ensuring the accuracy and reliability of test data, and shortening the product certification cycle.
• One-stop Service: Providing full-process technical support from pre-test, problem diagnosis and rectification to the formal test report, helping customers solve problems quickly.
• Global Recognition: Test reports comply with international mainstream regulations and standards, helping customers' products smoothly enter the global market.
