The Wuhan UHV after-sales team provided technical support for the lightning impulse voltage generator test device to customers in Shijiazhuang
2024-12-04Recently, Wuhan UHV after-sales technicians went to Shijiazhuang Cable Factory to provide product technical training. Shijiazhuang customers purchased UHV series lightning impulse voltage generator test devices and applied them to on-site testing. Wuhan UHV after-sales personnel provide product technical training for engineers to ensure that customers can proficiently operate and understand the principles of the device.The impulse voltage test system is a testing equipment that simulates high pulse voltage. In real life, pulsed high voltage is a common phenomenon. For example, in nature, lightning and thunder strikes generate extremely high pulse currents and voltages at the landing point, while inducing high pulse voltages in the surrounding area. In addition, the switching operations of switchgear in the power system can also cause transient pulse voltages. The amplitude of these transient pulse voltages often reaches tens or even hundreds of kilovolts, which can damage equipment and
