applicationCurrent transformers are for the galvanic separation, proportional transformation of alternating currents of larger currents into smaller, direct measurable values. There are two categories subject to their application: measuring transformers and protection transformers.
All current transformers manufactured by DEIF are for low voltage applications with a max. phase to phase voltage of 0.72kV.
measuring transformerMeasuring transformers are used to measure current, power, power factor and energy consumption combined with an equivalent measurement unit. Using its magnetic circle, current transformers allow a high transmission accuracy in the nominal current range, whilst simultaniously protecting the connected appliances against over current. The magnetic saturation in the measuring core ensures protection in the event of an over current.
Protection current transformersProtection current transformers are for the control of protecting relays which have the task to separate switched circuits in the event of over current. For a save function of these relays a proportional transfer ratio of the transformer up to a multiple of the nominal current is necessary. The dimensioning of this transformer unit secures a proportional current transfer, up to a multiple of the nominal currents, determined by the protection class.
Technical standardsAll DEIF current transformers are produced in accordance with the technical requirements of DIN EN 60044/1 (edition 12/2003)
Technical characteristicsApplication use: Indoors, without condensation
Protection current transformers Ambient temperature: - 5°C … + 40°C. Housing material: Polycarbonate, self-extinguishing Housing form: halve-cup-shaped, ultrasonically welded Isolation class: E Thermal rated nominal continuous current: 1.2 × IN Secondary rated currents: 5A or 1A Thermal rated short time current: 60 × IN (max.100kA) Max. excess temperature of the secondary winding: 75°C Isolating test voltage: 3kV UEFF; 50Hz, 1min
Safety instructionsThe protection current transformer’s physical characteristics has its many advantages and with all these built-in features it is very easy to attend to this transformer with their secondary circuits open. This can be very harmful to the operator or transformers as multiple kilovolt surges can occure. In order to prevent any mishaps an operation as described above ist forbidden. ordering instructionsFor the correct processing of your order, please make available the following specification: Transformer type, transmission ratio, accuracy class and rated burden

Test certificateOn request, we can provide you with a test certificate for a specific current transformer along with the CT. Please inform us when placing your order.
Sealed shutterOn request, we can supply a transparent plastic cover. The cover seals the connections on the CT in a way that leaves the type label visible. Please check availability on each individual data sheet.
excitation curveOn request, we can provide you with an excitation curve for a specific current transformer along with the CT. Please inform us when placing your order.
optional frequencyFrequency range for a standard CT is 50-60Hz. On request, we can provide you with a frequency range from 16 2/3 – 400Hz. Please inform us when placing your order.
cast resinCast resin is standard for all CT’s with a nominal current >4,000A. On request, all CT’s with a nominal current <4,000A can be produced with cast resin. Please inform us when placing your order. The min. and max. weight specification for each type refers to standard versions. The specification is different if cast resin is ordered for CT’s <4,000A.
mountingFoot angle for screw mounting and busbar mounting screws with isolating protection caps are supplied along with the CT. DIN-rail mounting for tubes, plug-ins and protection transformers is available on request for certain CT types. Please check availability on each individual data sheet.
