Solis Recommends Anti-Grid Surger In Solar Systems

Feed Solar

The Grid surge, or Switching operations can generate induced surge voltages that spread to supply lines.

These short- term current changes can lead to transient over voltages and the main sources fall into the following categories: (1)Input and excision of large loads; (2)Input and excision of inductive loads; (3)Input and excision of reactive compensation capacitor; (4)Short circuit fault of grid; Grid surge exists in any power grid, especially in factories with a poor grid or large load with often input and excision.

According to data, the electric surge caused by electricity load in the grid system accounts for about 70% of surges, while lightning surge is only about 30%.
