In an example, the data corresponds to production-related information, working status, fuel level and the like. The self-powered sensing device 102 is light in weight.
[0025] The self-powered sensing device 102 includes a split core current
transformer 104, a clamping mechanism 106, a power management unit 108, an energy sensing logic unit 112, a processing unit 116 and a supercapacitor 118. The block diagram 100 includes a power cable 120 and industrial equipment 122.
[0026] The power cable 120 is an electrical cable, an assembly of one or more
electrical conductors, usually held together with an overall sheath. In general, the power cable 120 is used for transmission of electrical power. Power cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or exposed. In an embodiment of the present disclosure, the power cable 120 is

connected to the industrial equipment 122. The power cable 120 provides sufficient power to the industrial equipment 122 to operate. In an example, the industrial equipment 122 includes but may not be limited to a plurality of equipment used in solar panels, industries, factories, plants that require constant monitoring and maintenance. The industries include but may not be limited to manufacturing industries and plants which consume a lot of energy for performing a number of operations. In an example, the industries include oil and gas industry, chemical industry, energy generation plants and sectors with critical machinery installed and the like.
[0027] The self-powered sensing device 102 includes the split core current
transformer 104. In general, the current transformer (CT) is a type of transformer that is used to measure alternating current (AC). The current transformer produces a current in its secondary which is proportional to the current in its primary. The current transformer provides a secondary current that is accurately proportional to the current flowing in its primary. The split core current transformer 104 is a transformer having two-part core or a core with a removable section. The split core current transformer 104 of the self-powered sensing device 102 is placed around the power cable 120 to harvest energy from the current flows through the power cable 120. In addition, the split core current transformer 104 is placed around the power cable 120 to operate the self-powered sensing device 102 without the need of disconnecting the power cable 120. Further, the split core current transformer 104 is clamped around the power cable 120 through a clamping mechanism 106. In an embodiment of the present disclosure, the split core current transformer 104 with two core sections are clamped to the power cable 120 with a screw-based spring action clamping mechanism. The screw-based spring action clamping mechanism avoids spark and noise when the sensor device is installed on high industrial equipment. In addition, the screw-based spring action clamping

mechanism enables high contact area with the power cable on which the sensor device is clamped on. In another embodiment of the present disclosure, the split core current transformer 104 may be clamped on the power cable 120 using different clamping mechanism.
[0028] The current flowing through the power cable 120 induces a magnetic field
around the power cable 120. The magnetic field around the power cable 120 generates energy which is captured by the split core current transformer 104. The energy captured by the split core current transformer 104 is used for the operation or working of the self-powered sensing device 102. In an embodiment of the present disclosure, the power cable 120 induces a very little amount of magnetic field. The self-powered sensing device 102 is designed in such a way that it operates perfectly under such little magnetic field.
[0029] The sensing device takes power or energy that is lost from the power cable
120 to make it the self-powered sensing device 102.

By adjusting alloy composition and grain directions, required performance of sensing parameters can be achieved. For example: the grain-oriented electrical steel usually has a silicon level of 3%. By using the cold rolled grain-oriented electrical steel, the magnetic flux density is increased by 30% in the coil rolling direction, although its magnetic saturation is decreased by 5%. The cold-rolled grain-oriented electrical steel is often abbreviated to CRGO.
[0030] The different materials for the core mentioned above with lower losses and
higher flux retention, allows the split core current transformer 104 to harvest the

maximum amount of energy from the magnetic field of the power cable 120.
