When should you spend extra for closed-loop accuracy versus accepting the simplicity of open-loop? A side-by-side comparison with a practical decision matrix and three real-world example specs.
EN 50155 references half a dozen other standards, runs to 130+ pages, and specifying a "compliant" sensor without reading it is risky. Here is the practical filter that matters when you spec sensors for rolling stock.
A 0.5% drift in current measurement sounds trivial — until you compound it over a 25-year solar farm. Here is a worked example that shows why MPPT-grade sensors save money over the project lifetime.
When an IGBT short-circuits, you have less than 10 microseconds to turn it off before catastrophic failure. Current sensor response time eats up most of that budget. Here is the math.
