3 PPLICTION The CT makes it possible to measure high values, and indicate, these using instruments of much lower ratings. Owing to the high costs of the cable, we recommend the use of a CT for measurement above (unless otherwise specified. ) THERMIC CURRENT (Ith) Is the highest (effective value) that the CT can support for second, without damage, owing to ecessive overloads, with secondary short circuited. DYNMIC CURRENT (Idyn) Is the highest (peak value) that the CT can support for second, without damage, owing to electromagnetic efforts, with secondary short circuited. HIGHEST VOLTGE LIMIT RNGE Is the highest voltage (effective value) that the CT can support. GENERL DESCRIPTION TEST VOLTGE Is the voltage that the CT can support (at industrial frequency, for the insulation reference) for minute between and secondary. STURTION FCTOR(Fs) - SFETY FCTOR(n) Is the ratio between the value that causes the magnetic core saturation and the nominal value. The lower is the "n" value, better the instrument is protected.

11 Revalco is able to supply the certification of the measuring groups in case the Customs Technical Department requests it. The certification of the whole plant is to be requested at the competent UTF offices of the area. In case of a measuring group with three systems composed of transformers and one meter, inspection certificates are necessary. When the measuring group to be inspected is a system, 4 certificates are requested as the interested CT are only two. TCSC CCESSORIES FOR LL MODELS FOR SMLL SERIES CERT-U CERTIFICTIONS TCSC / TCSC SELBLE TERMINLS COVER CCESSORIES FOR NNO SERIES Transparent sealable terminals cover (min. pieces) TCSC: Sealable terminals cover for TCS, TCS, TCS, TCS, TCS0, TCSV, TCSV TCSC: Sealable terminals cover for TCS08, TCS0, TCS8, TCS, TCS, TCS, TCS4, TCS47, TCSV SELBLE TERMINLS COVER SCT ELECTRONIC PROTECTION (PTENTED) S.C.T. SECURITY CURRENT TRNSFORMER Electronic circuit for automatic protection against dangers caused by the deconnections of secondary terminals of transformers (open circuit). It automatically makes a short circuit on the secondary winding in case of accidental loss of load. Residual on terminals remains lower than V RMS (safety limit valid on all uses - PELV SELV FELV). In standard use, if nominal voltage is not higher than V in C and V in DC, the system grants the double protection against direct and indirect contacts. The intervention is instantaneous and the voltage on the secondary terminals of transformers in limited up to V RMS; when the normal working conditions will be restored the electronic circuit stops its action and its influence to the transformers stops also. Completely static it is composed by few essential components assuring long time duration. Standards: IEC4; IEC47..4; IEC. / CEI4-8-4; CEI4..4.; CEI4.. - CEI4. - CEI CEI47.. Characteristics: - reduced installation costs - possibility to take out the connected device without precautions or safety risks - the electronic circuit is self supplied by the secondary terminals in case of load loss only - in standard and nominal working conditions the device doesn t influence the correct function of transformers pplications: - where it is necessary to encrease the safety coefficient - places with fire risk, eplosion risk, high humidity level, hospitals - mines and quarries - naval use - military use - electrical situation on which not qualified people is present - modular boards with high safety level - low or etremely low voltage applications COR... / ECOR...

The signal eiting from this sensor is conditioned in the way to represent eactly the value. GENERL DESCRIPTION Function of sensor is based on Hall effect fisic principe: when a magnetic field is applied in a perpendicular way to a cable, a transverse voltage to the flu direction is generated (Hall voltage). This type on C.T. can be used as alternative to the shunts when high voltages are in the field and it is necesasry to have more higher galvanic separations.

63 The purpose of the shunt is to permit the passage of the which eceeds the capacity of the instrument. The latter will therefore be supplied only with a which corresponds to its capacity, thus avoiding the risk of damaging the measuring equipment. The shunts are resistances of very little value and for this reason they are at times formed by conductors with a bar of limited length and substantial rectangular section. For heat dissipation several bars in parallel are used, terminating in two clamps with a large contact surface. longside the two clamps there are a further two clamps which serve to connect the ammeter.these clamps have lesser section as the necessary for the instrument is much lower than that of the shunt. Infact, it is not so much a question of the shunt being parallel with the instrument as the instrument deriving from the clamps of the shunt, of which it utilizes the drop in voltage, withdrawing a part of the of the circuit, proportionate with the total.

Standards require the following values: -, -, Primary values different from the standard can be manufactured on request. To ensure the unit functions perfectly Revalco insists the following points are observed:. They can be fitted in either a horizontal or vertical position (if horizontal there is a greater dissipation of heat). The contact surface must be completely used.. The contact surface must be clean; after connecting, cover with special grease. 4. The screws and bolts must be perfectly tightened.. The shunts must be sufficiently ventilated. Due the fact that the shunts are not insulated, it is better to protect them against accidental contacts.
