The current transformer TOLU-10 changes the initial current parameters to values that can be measured by measuring devices. Automation devices and relay protection circuits can also be installed at their output.
With its help, secondary circuits are isolated from the high voltage received from the mains. This ensures the safety of their operation. Such transformers are installed in AC switchgear devices.
They operate with a voltage of up to 10 kV. The current frequency is 50 Hz. Their manufacture corresponds to climatic execution "U" 2. Production technologies provide for compliance with the requirements of DSTU 15150-69. The main reason to buy it is the quality of work and durability ensured by the use of nanocrystalline materials in the manufacture of the core. It does not lend itself to magnetization and allows the device to operate for 50 years without changing its metrological characteristics.
