FIELD: electricity.SUBSTANCE: invention is referred to electrical conductor sheath equipped with current sensors, which may be applied in electrical appliances. The sheath surrounds a linear conductor and comprises at least one inner chamber with at least one fibre-optic sensor or a sensor with current transformer wound around the sheath and allowing current measurements. The chamber is closed in essence and comprises only openings of small diameter at its outer side, through which the sensors may be inserted or removed for replacement purpose and through which the sensors are connected to an electrical appliance. The sheath is equipped with grooves at its surface or separate tubes to direct sensors and form sensor turns.EFFECT: development of the sheath, which allows mounting or replacing of the sensor without disturbance of current circulation in the sheath and tightness failure in the sheath.8 cl, 6 dwg |
