The most common power failure is the voltage dip. Even a small (brief) voltage dip can result in hours of business interruption and a substantial loss of productivity. They can arise both on the utility supply side , as well as on the consumer side, such as, when starting large machines. For digital devices, a voltage dip can be even more dangerous than a power interruption. PC servers, for example, can "hang up" as early as 8 milliseconds undervoltage.
The "Sag Directivity Module" identifies voltage dips and automatically determines the direction relative to the monitoring point. This is typically referred to as "upstream" or "importing" a fault when it comes from the feeder side, a higher level or from another branch. "Downstream" or "self-generated" when the disturbance comes from the consumer side, or a deeper level; just in relative terms from the connection point of the device.
Knowing where the disruption is coming from, whether trapped by the RU, or generated within the fabrication itself, is the first step in resolving the disruption and protecting productivity. Fast and cost efficient.
Reactive power compensation systems support the in-house network by minimizing reactive currents and improving the PF (formerly cos?) Power factor. For this purpose, capacitors are switched into the network, some of which are constantly on the grid and others are switched on as needed (sometimes several times a day). Although such circuits are common and normal, transients can be generated which damage regulators and equipment. Most importantly, such transients in PC's and controllers can cause malfunction, such as "hanging up" or data loss.
Such switching transients can propagate over long distances within the network and in some cases even amplify (resonances).
The "CapSwitch module" identifies and characterizes these types of perturbations and their direction, relative to the monitoring point, and enables rapid intervention and mitigation of the damage.
In the U.S.A., there are 12.4 million more than 750-watt motors. Of these motors, approximately 2.9 million fail each year due to an electrical fault.
The fact is: the cost of an engine is only in the range of 2 to 5% of its maintenance costs during its operation. It goes without saying that maintenance and longevity are in the foreground of every facility manager.
Various parameters shorten the life or are an indicator of the condition of an electric motor. The motor quality display field of the MAVOWATT 40 and 70 shows these parameters in a clear, color-coded status panel:
