Purpose of Current transformer TTE-30 250
Similarly current transformers are intended for transmitting a signal of measuring information to measuring devices. Protection and control devices and are used in AC networks with a nominal frequency of 50 Hz and a rated voltage of up to 660 V.
The Current transformers are installed, for example, in input-distribution devices for accounting for energy consumption.
So, The company’s product range includes current transformers with a built-in bus – ТТЭ-А, and with a universal window (without a built-in bus) – ТТЭ-30, ТТЭ-60, ТТЭ-85, ТТЭ-100, ТТЭ-125.
Advantages of Current transformer TTE-30 250
1. The transformer housing is non-separable, made of self-extinguishing polymer material.
2. The integrated bus bar of the transformer TTE-A is copper tinned, which allows connecting both copper and aluminium bus bars.
3. Rated current up to 5000 A.
4. Universal window of transformers ТТЭ-30 – ТТЭ-125 allows using them on buses and cables of various sections and configurations.
5. The secondary terminals are covered with a transparent cover for safety. The cover can be sealed.
6. Two mounting methods: on the bus or on the panel.
7. Two versions: black with MPI for 4 years and color with MPI for 8 years.
Operation and installation features:
The Current transformer TTE-30 250, current transformers are available in two series – for installation on a bus / conductor (ТТЭ 30-125) and with a built-in bus (ТТЭ-А).
In addition, there are two versions – black current transformers with an interesting interval of 4 years and color current transformers (yellow, green, red to match the color of the phases) with an interesting interval of 8 years (TFE color).
Moreover, Black current transformers are delivered in individual packages, color current transformers are supplied in sets of 3 pcs. different color.
However a feature of TTE color is the guarantee of metrological compatibility, because the kit consists of transformers of one batch.
