3 Time sensors Detect the signals, where they rise Low voltage transformers In the practice of industrial electrical measurement, some devices of the measurement chain adapt the signal to make it compatible with the measuring instruments. In the complex of these devices, the transformer is one of the most important examples for diffusion and universality of use. From the simplest applications in which analog and digital indicators are used, to the more complex which is expected the use of transducers, KWh meters, multifunctions or protection devices, the supply of current and voltage inputs is generally performed by means of transformers. The use of transformers, besides conditioning the signal, allows to obtain a complete galvanic isolation between the primary and secondary circuit, granting the necessary level of insulation between apparatus user and protection or measuring instruments. Current Transformers They adapt the current values to the measuring and protection equipments, delivering a reduced a secondary current proportional to the standard values 5A or 1A. IME current transformers comply with EN Standards and depending on the intended use they can be divided into: Measuring Classes: 0,5-1-3 / Applications: counting and industrial measurements Accuracy Classes: 0,2-0,2s-0,5s / Applications: counting and measuring with an high degree of reliability at the lowest currents (1% in classes with 0,2 or 0,5s) Protection Classes: 5P5-5P-5P-5P / Applications: combination with protection relays Summation Classes: 0,5-1 / applications counting and industrial measurements on different lines belonging to the same voltage system. Voltage Transformers They adjust the values of the primary voltage to the measuring or protection devices delivering a reduced secondary voltage to the standard values V (other values upon request). IME voltage transformers comply with EN Standards and depending on the intended use can be divided into: Measuring Classes: 0,5-1 / Applications: counting and industrial measurements Accuracy Class: 0,2 / Applications: counting and measuring with an high degree of reliability Protection Class: 3P / Applications: combination with protection relays 3

Ipn s1 k P1 K Isn s2 l P2 L LOAD 1 3 However, to overcome this situation, for all the current transformers, IME proposes a static accessory (ATAP0), allowing the instantaneous reclosing of the secondary circuit of open CT due to circuit interruption or equipment removal as well as instantaneous automatic recovery on the return to normal conditions. Protection degree IP secondary terminals (for models TAS... TAU... TAQ... BSA... only with the use of sealable terminal covers). 4
