Jun 10 2018· Drive VFD overvoltage protection for common low HP drives is based on the measured voltage on the DC bus of the unit and not the input AC voltage It is important to realize this fact to aid in troubleshooting Any and all events that could cause a jump in DC bus voltage could lead to a dc link overvoltage fault event

Simulation of Stress on Elements of Metal Pushing V-belt

Transient suppression devices can be used in series with the load to either attenuate or reduce the energy value of a transient preventing its propagation through a circuit or they can be used in parallel with the load to divert the transient away usually to ground and so limit or clamp the residual voltage

CRITERIA FOR MINIMISING TRANSIENT STRESS IN

However belt turnovers are also subjected to bending stresses due to the weight of the belt Although bending stresses have in the past been ignored these stresses are significant and should not be neglected This paper quantifies and presents a method for calculated twisting and bending stresses and also the belt sag
