The paper presents the test set up and the measurement procedure of the relative value of the shielding effectiveness coefficient of the Y adapters. Such elements are widely used in IT networks in industrial automation systems. They are used for transmitting analogue and digital signals between the automation devices and different kinds of sensors, and for construction of industrial networks for data transfer. The paper presents the method of measuring the shielding effectiveness of such elements by measuring the signal attenuation between the radiating element and the internal wires of the tested element. The described test set up has been constructed in such way that minimize the signal penetration by the free space, that is outside the measuring zone. The test setup can be especially useful during the control of a process production and during preparation of new solutions. The construction and exemplary results of the tests were presented.
