LOADING TRANSFORMER

A Loading Transformer with the designation Type SI/LTR-(w) is a specialized transformer designed as a window-type or toroidal transformer. These transformers are used for providing adjustable loads to electrical circuits during testing, calibration, and performance evaluation, similar to other loading transformers. The “window model” or “toroidal” design implies that these transformers have a toroidal or ring-shaped core with a secondary winding that can be passed through the core’s central opening, facilitating the measurement of currents without requiring direct contact with the primary circuit
