The GR-GEAM7K-33 series power grid simulation source is an AC power supply with high precision, high dynamics, high standards, and comprehensive power grid characteristic simulation. It can perform various grid adaptability tests on devices connected to the grid, and can output stable voltage and frequency. It can also provide power supply environments with various power quality related characteristics such as voltage changes, frequency changes, harmonics, interharmonics, imbalances, and flicker according to relevant national standards. In addition to providing a power environment for electrical equipment, the power grid simulator can also receive the energy returned by the load and feed it back to the power grid, which can save energy and improve the testing environment.
