Current transformers TSH-0.66; TSH-0.66A are designed for transmission of measurement information signals to measuring, automation, signaling and control devices in alternating current electrical circuits with a frequency of 50 Hz or 60 Hz.
Current transformers ТШ-0.66; ТШ-0.66A meet the requirements of the Technical Regulation of legally regulated measuring equipment, approved by Resolution No. 94 of the Cabinet of Ministers of Ukraine dated 13.01.2016.
ТШ-0.66 current transformers with a rated primary current of more than 300 A and T-0.66A current transformers of all designs meet the requirements of DSTU EN 61869-1, DSTU EN 61869-2 (the load of the secondary winding is in the range from 25% to 100% of the value of the nominal load).
ТШ-0.66 current transformers with a rated current of up to 300 A inclusive (except for current transformers with an amorphous alloy core) are manufactured in accordance with the manufacturer’s technical specification (the load of the secondary winding is in the range from 75% to 100% of the value of the nominal load).
Current transformers TSH-0.66; TSH-0.66A (without busbar, with a hole for the busbar), installed on the busbars of consumers’ distribution devices.
