Soft start energy storage failure

Cause of an SCR failure on a soft starter

Allowing the Soft Starter to sustain high currents for prolonged periods can elevate heat levels, leading to SCR degradation and eventual failure. Higher heat diminishes the reverse blocking capability of the SCR devices, making them susceptible to failure. Transient spikes can also contribute to SCR failure.

how does a soft start work

A soft start motor gradually ramps up the speed of the motor over time, reducing the strain on the system. This allows for a more efficient and smoother operation compared to direct starting. What is a Soft Start? A soft start is a tool used to limit the amount of torque and current used by an electric motor during its startup.
