Passive Current Transformer Series In-I
Pulse Current Transformers Description Due to the selected materials, REO pulse current transformers of the IN-I series can represent current with high accuracy and the corresponding transformation ratio – making them particularly suitable for power measurement, current monitoring and analysis, and for use in solar inverters. They are also ideally suited for use in active filters, as they can be designed for measuring current peaks. The primary current is measured via a current conductor that passes through the closed toroidal core. The magnetic field generated by the current flow through the conductor is absorbed by the toroidal core and, according to the transformation ratio of the secondary winding, generates a smaller current for measurement purposes. This method reduces a high measurement current to a significantly smaller current and additionally separates it from the primary circuit by means of safe galvanic isolation. Advantages Very precise current measurement Class 0.2 Pulse current measurement Low-loss core (core losses <10W/kg at 20kHz/200mT) Housing made of UL VO material (Conductor must be positioned) Diverse applications, e.g., for:Active filters, EMC measurements, and pulse current measurements Typical Applications Measurement and Testing Technology Technical data Type 50 100 200 Primary current [A] IPN r.m.s 0 – 50 0 – 100 0 – 200 Max.
