The TF1-75.150/1 is an aircraft current transformer designed for scaling high alternating current values for operation with onboard measuring instruments.

Within the electrical measurement system, the transformer converts primary AC currents to a standardized secondary current suitable for connection to aircraft ammeters and monitoring devices.

The transformer is applied in aircraft onboard electrical systems for monitoring current parameters of engines, transmissions, and auxiliary systems.

The product is also known under alternative designations TF1-75.150/1A, which refer to the same product type.
