Problems solved by technology
[0002] At present, there are many detection equipments, such as: application number 200910079341.1; The detection environment is very complex. If you want to save costs and use two detection devices to combine and then transmit, the requirements for the combiner are very high. It is necessary to control the electrical performance such as phase difference and return loss within an excellent range; moreover, Among them, in order to prevent the influence of the electric field environment as much as possible, the combiner should have the input signal and the output signal on the same side, so a new combiner that can realize the input and output can be set on the same side and can reduce the phase difference and return loss The combiner controlled within an excellent range is the solution to the problem of multi-channel integration in the communication system

The invention discloses a power system detection and communication system with a second filter. The system comprises two power detection devices with the same frequency; the signal output ends of the two power detection devices are respectively with two signal input ends of a combiner; the signal output end of the combiner is connected with a communication device; and the communication device transmits signals coupled by the combiner to a ground analysis center for analyzing power signals. The combiner is designed excellently, so that the output signals of the two power detection devices can be combined together, and therefore, the power system detection and communication system has high electric field interference resistance. With the power system detection and communication system adopted, low-cost power detection can be realized.
