If Uc is small, the value of Up is also small; s with smaller Up can provide better surge protection. Whether to choose smaller Uc depends on the voltage stability of the grid. If you choose s with smaller Uc for the grid with instable voltage, the s will frequently work while the grid voltage fluctuates, resulting in shortening s product life. If you choose larger Uc, and the value of Up is accordingly large, the surge protective efficiency will not be so fine. If you are unsure of the voltage stability of the grid, it is suggested to calculate Uc using the following formula: 2Un<Uc< 3 Un The impulse current and residual voltage curve in Ures=-40kA (WTH-165/B/1-420(L-)) The impulse current and residual voltage curve in Ures=-40kA (WTH-165/B/1-690(L-)) Watchful Eye olutions, Inc. 120/165-3
