FIELD: electricity.
SUBSTANCE: invention relates to control of thermoelectric devices. Essence of the invention: the method contains stages of voltage supply of Peltier element, voltage disconnection after a certain period of time, measurement of voltage in Peltier element and comparison of the measured voltage with reference value. The small-sized electric device (for example, the electric shaver) with Peltier element has the protection device excluding risk for user as a result of wrong functioning of the Peltier element.
EFFECT: simplification, improvement of reliability of testing, providing user protection.
