EMC Electromagnetic Compatibility Lab
The harmonics measuring system consists of a harmonics analyzer and a programmable power source module. It’s used to assess the adverse influences, e.g. harmonics interference, voltage drop and flickering, upon the public mains when the product is electrically connected to a mains outlet. Thus it helps to verify the product to meet the essential requirements of relevant standards.
Programmable power source
Harmonics testing software
It’s used to verify the conformity of GB17625.1 and IEC61000-3-2 standards by comparing the measured harmonics contents with the permissible emission limits.
It can also be used to verify the conformity of GB17625.2 and IEC61000-3-3 standards by assessing voltage drop and flickering produced by the tested products when connected to the public mains.
