Sag Protection
Sag Protection
(OP)
Anyone knows a good industrial brand for Sag Protection, using energy storage devices such as capacitors, flywheel, or battery for > 1000KVA applications?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

Disclaimer: I don't work for them and have no knowledge of how good their stuff is; all I know for sure is they have installed and commissioned a pilot project / feasibility demonstration plant on one of my utility's 28 kV feeders. Near as I can tell their product is intended to supply / absorb both real and reactive power in the short term. Exercise your due diligence...
Incidentally, the subject line of the OP used terminology unfamiliar to me . . . and I immediately wondered how one would protect against conductor sag due to thermal overload; it was only as I read on that I realized - if I've grasped it correctly - that the concern was voltage sag protection...
Second incidentally: My utility has a conductor sag detection facility used to derive realistic continuous and limited time ratings for specific 230 kV circuits that are often very heavily loaded, especially during the summer months [these circuits collectively comprise a "flowgate"]. Ultrasonic proximity detectors are used in conjunction with known line loadings and local ambient temperatures to calculate very accurate effective wind speeds which can then be plugged into the thermal monitoring program to enable said lines to be loaded to their maxima without crossing the fateful line into overload and premature conductor aging.
