CTKN Series current transformer

Product Overview

A CT uses electromagnetic induction and consists of two windings: a secondary winding with several turns connected to safety or measurement devices and a primary winding with a few turns connected in series to the high-current circuit. The secondary winding, which is typically tuned to 5A or 1A for the majority of industrial applications, receives very little current while the primary winding receives a substantial amount. This proportionality, sometimes referred to as the transformation ratio, protects personnel and equipment from potentially hazardous voltages while enabling precise current monitoring.

High accuracy for energy metering, linearity to reduce measurement error, and sufficient insulation to sustain a high voltage between windings are all necessary for CTs. The secondary winding should never be left open circuit while using a CT. This is because an open circuit may produce extraordinarily high voltages that might damage electrical equipment.Lastly, because they allow for more accurate current monitoring and better problem diagnostics, current transformers are essential to guaranteeing the dependability, effectiveness, and safety of contemporary electrical systems.
