Measuring Transformer

Part of DEIF’s current transformer range, the measuring transformers convert high current to lower nominal current value, thus making it possible to use instruments and relays with standardised values of rated current. DEIF offers 41 different physical sizes of the measuring transformers.

Power Current Transformer

The PCT is a combined transformer with both a voltage and a current output for DIN mounting.It decreases mounting space, minimises the numbers of connections on the terminals, and this reduces mounting costs.A fuse is directly mounted on the priamary conductor which gives a short unprotected part of the terminal and results in high reliability.

Primary winding current transformer

Based on the physical operating principle of current transformers, the required core volume transferring an amount of power, increases rapidly with a decreasing nominal current. As there are limits on increasing the transformer size, Primary winding current transformer are being used. Primary Winding Transformer, WSK, is the perfect choice for low currents in the range 1 A to 100 A.

Split Core Current Transformer

The compact SCT split-core current sensor from DEIF is especially designed for retrofitting on existing installations. The SCT series is supplied with color coded leads. The accuracy class 3 or 1 for all these CT’s is perfect for high accurate current measurements.Correct closing of the current sensor is guaranteed by a distinct sound of a “click”.

Split Core Transformer

DEIF’s split-core current transformers are cost-saving and easy-to-install units for responsible and efficient energy management solutions and for retrofitting existing installations. Because the split-core transformers can be mounted with a click and without interrupting the power supply, installation is smooth and executed in no time. KBU is the ideal split core transformer for retrofit projects where DEIF covers the range from 100 A to 5,000 A.

Protection current transformer

Protection 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 protection transformers are used for overcurrent and earth fault protection in balanced protection systems. DEIF offers 15 different physical sizes of the protection transformers.The housing of the transformers is made of impact-resistant thermoplastic to ensure a highly reliable quality. The terminals of the transformers are protected by a cover.

Summation current transformer

Summation current transformers are suitable for the summation of several synchronized alternating currents with similar phases but with differing load phase shifts. It is also possible to have the summation of currents with varied nominal voltages of similar phase positions. Part of DEIF's current transformer range, the summation transformers summarise the secondary currents of any number of main current transformers to a common secondary signal . DEIF offers 2 different physical sizes of the summation transformers. The housing of the transformers is made of impact-resistant thermoplastic to ensure a highly reliable quality. The terminals of the transformers are protected by a cover.

Shunt Resistor

Shunts provide an accurate DC milivolt signal to drive moving-coil ammeters, overload protection and control units for higher ampere range. Shunt Resistors introduced by two generally type as 60 and 150 mV. Type 60 mV divided into A and B form. Also , Type 150mV divided into Three form as A , B and C.

Three channele AC earth fault guard

The three channel digitally controlled KCM363x monitors up to three earth current channels in a non-grounded (IT) or grounded TN network and its protective earth. Unit can be used for either Restricted or Unrestricted earth fault detection.There is individual relay for alarm or trip of load breaker.
