The testing items for power transformers and reactors are as follows: (1) Chromatographic analysis of dissolved gases in oil; (2) The DC resistance of the winding and the bushing (to determine the welding quality of the coil internal joints, lead to coil joints, tap changer to lead, and whether there are open circuits and short […]

In this post, we only talk about distributed PV power plant. Following issues, we need to consider when we connect a distributed PV plant to local grid network. Grid voltage adjustment: According to the requirements of the power grid company, adjust the grid voltage of the distributed photovoltaic power station to ensure its matching with

Resolving the issues of voltage fluctuations and harmonics for a distributed photovoltaic power plants is an important task to ensure the stable operation of the power grid network. Through years of our experience, we believee, the following measurements we need to take; Voltage regulator: By installing voltage regulator , real-time monitoring and adjustment of the
