  • PURPOSE of Current transformer TTI-A 200

It is intended to convert the current to a value convenient for measuring, transmitting the signal of measuring information to measuring, protection, automation, signalling and control devices in AC electric circuits with a frequency of 50 Hz with a nominal voltage of up to 0.66 kV inclusive.


They are used in commercial energy metering systems, in measurement and control circuits with high currents. Allows you to perform galvanic isolation of the power and management circuit to increase safety.


When using the Current transformer TTI-A 200, TTI-A transformer, the power wire is connected to the terminals of the transformer primary winding, when using the TTI-30 transformers – TTI-125, the current-carrying bus passes through the transformer window and is the primary winding.
The current that is to be measured is removed from the secondary winding, and the current flowing through the secondary winding of the transformer is proportional to the current flowing in its primary winding and can be determined by calculation.


Each transformer comes with a cover that closes the terminals of the secondary winding.
TTI-A transformers are equipped with screws and nuts for mounting conductors. Transformers TTI-30 – TTI-125 are equipped with a bracket for mounting the bus in the window of the transformer.
No additional accessories required. Get Current transformer TTI-A 200 now.
