An apparatus (1) for measuring the loss factor of an insulator (2) for medium or high voltages, equipped with a tap adapter (3) forming a point for picking up an electrical signal (4), comprises a reference capacitor (9) having a first electrode (10), which can be connected to the tap adapter (3), and a second electrode (11); a first voltage detection module (12) operatively connected to the first electrode (10) of the reference capacitor (9) for detecting a signal representative of the voltage applied to the reference capacitor (9); a generator module connected to the first electrode (10) of the reference capacitor (9) in order to inject a direct electric current into the insulator.
