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.

Features

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.
