Strømtransformatorer skalerer store strømverdier ned til små, standardiserte verdier for måleformål. De gir en sekundærstrøm som er nøyaktig proporsjonal med strømmen som flyter i primærkretsen. Strømtransformatoren utgjør en ubetydelig belastning for primærkretsen.
Lengden på CT-klemmens kabler er 60 cm.

I’ve been using these to monitor my workshop’s main feed and the secondary current stays spot-on proportional, even under heavy load. The scaling ratio is exactly what’s printed on the label, so my readings have been consistent since day one. Makes wiring up my multimeter a breeze.
Was a bit skeptical about the accuracy, but the secondary current stays proportional to the primary flow even when I pushed it near the max rating. The standardized output made it trivial to hook up to my existing meter without any fiddly calibration. Solid little piece for the price.
The secondary current output is spot-on proportional to what I'm measuring, so my readings are finally consistent. Calibration took me about ten minutes to get right, but now it's just set-and-forget for my panel setup.
