Power line induction in the power transformer low-voltage windings applying operational shock voltage, through electromagnetic induction to make the transformer high-voltage windings of the insulation to withstand the overvoltage test test.
The test is applied to the voltage waveform is simulated within the power system due to switching operations or faults generated by a waveform, known as the operating shock voltage wave.
According to China's power industry standards, the operational shock induction withstand voltage test can be applied at the site of a power substation to test the insulation of a power transformer.
The power line contact test simulates direct contact between power lines and communication lines; the power line induction/contact test is performed on the twisted-pair ports of telecommunication terminal equipment and external AC or DC dedicated power ports.
Power line induction contact generator is specially designed to simulate the power line or electrified railway system on the adjacent communication line induction and power lines and communication lines in direct contact with the interference phenomenon produced by the establishment of a **** the same basis.

8, spurious definition: refers to the standard test signal modulation in addition to the carrier frequency and due to normal modulation and switching transients caused by sidebands and neighboring channels outside the discrete frequency radiation (both far-end radiation). Spurious radiation according to its source can be divided into two types of conducted and radiated.
9, conduction spurious: the level power of any discrete signal measured at the connector of the antenna 50 ohm load.
10, radiated spurious: test equipment chassis, structure and interconnecting cables caused by spurious nuisance. Test conditions preferred in the dark room in the airwaves, or outdoors.
