A deep diagnosis of power issues is extremely costly for several reasons.
Power issues like a surge that knocks down a PLC or a delicate control may happen within a millisecond. On top of that, issues like overvoltage, ground leakage may be temporary or may be long-standing. Issues like harmonics and imbalances tend to exist constantly.
Designing a system that can capture a sub-millisecond current transient and at the same time can offer an amount of analytics like Machine utilization, Machine health, etc. needs a lot of careful planning of Firmware and Edge computation.
Signaguard has some of the most advanced features for power quality diagnosis and is available at the cheapest price.
