Indoor Current Transformers Cast Resin Insulated 1, 13.8, 17.5, 4 and 36 kv 96-1054 Description The current transformer series is built according the dimension standard DIN 4600, Narrow.

3 Indoor Current Transformers Cast Resin Insulated 1, 13.8, 17.5, 4 and 36 kv Description The current transformer series is built according the dimension standard DIN 4600, Narrow. The standard giving dimensions for only the herein called medium size also has developed a longer version to provide more core space. The series of transformers covers the current range Amps for 1 36 kv. The 13.8 kv and 17.5 kv versions have the same dimensions as the 1 kv version. transformers are available as single ratio, primary reconnectible double ratio and secondary reconnectible double ratio (or multiratio) types. 3

Degree of protection is IP 30. The terminals are provided with M5 screws for the termination of the secondary wiring and with throughgoing holes for direct earthing of the secondary circuit by M6 screws. 6 terminals can be supplied with this construction. Maximum 11 terminals with earthing bridges can be mounted when more than 6 terminals are required. Of these, 9 pcs may be used as core secondary terminals. The terminal cover is sealable.

5 Indoor Current Transformers Technical data and ordering information Cantilever strength: 5 kn Environment The ambient temperature range is from 5 o C to 40 o C (IEC recommendations). The transformers must be protected against unusually heavy deposits of dust or similar pollution, as well as against direct sunshine.

6 Indoor Current Transformers Technical data and ordering information Use at high altitudes In mountaineous areas the height above sea level may be higher than the height specified in the IEC standard as design criteria (= 1000 m). The thin air at high altitudes affects the cooling of the transformers as well as the required creepage free air distance to earth and between phases. The manufacturer should be consulted in such cases. The problem with creepage and free air distance can be solved by choosing transformer type designed for higher voltages. The requirement for impulse test voltge (BIL-level) should preferably NOT be higher than normal for the service voltage used as this may have a negative effect on the available output from the secondaries. The transformer specification can in such a case be for example: Service voltage Test voltages 4 D 17.5 kv 38 kv 1 min. / 95 kv impulse The transformer type 17.5 D would have been suitable if used below 1000 m. Permissable torques for screw connections Strenght class for the screws is 8.8. The length of the screw within the nut part should be at least 1.4 x screw diameter.
