Transient surges are a change in fundamental frequency that occur thousands of times a day when using a VFD. Standard surge protection devices are voltage triggered only and do not account for these transient surges that can lead to confusion in electrical systems. Examples include false zero crossing, false triggering of diodes and timing issues.
“The SineTamer transient protection system will be the saving grace for many facilities managers,” explained John Mitchell, global business development manager at CP Automation. “The sine wave has actually remained the same since the late 1800s. However, the sensitivity of the equipment that is connected to the grid is now much more sensitive. Therefore, businesses experiencing inexplicable downtime will benefit from eliminating these low-level switching transient events.”
