Technical Knowledge : Introduction to EMC Laboratory Site: Harmonic Current Emission (Harmonic) Section
I. Test Items
The harmonic current emission test stipulates the limit requirements for the input current harmonic components that the tested equipment may generate under certain conditions.
It is applicable to electrical and electronic equipment that is intended to be connected to the public power supply system.
II. Test Purpose
To ensure that the harmonic disturbance level of electrical and electronic equipment does not exceed the compatible level specified in IEC 61000-3-2 and IEC 61000-3-12 standards.
III. Test Principle
By monitoring the size of the current harmonic components when the tested equipment is connected to the public low-voltage power supply system, it is determined whether it meets the standard requirements.
IV. Equipment Capabilities
• Harmonic Analyzer (30 kVA three-phase power supply)
• Includes 30 kVA AC/DC programmable power supply, supporting single-phase and three-phase AC flicker compliance testing.
• Complies with standards IEC 61000-3-2 and IEC 61000-3-12
• The system is reserved for future expansion to 45 kVA and can be upgraded in specifications according to subsequent product requirements.
V. Technical Advantages and Customer Value
• Precise and Efficient: Utilizing advanced anechoic chambers and testing equipment to ensure accurate data and reliable testing, shortening the product certification cycle.
• One-stop Service: Providing full-process technical support from pre-testing, problem diagnosis and rectification to the formal testing report, helping customers solve problems quickly.
• Global Recognition: The test reports comply with international mainstream regulations and standards, facilitating customers' products to smoothly enter the global market.
