Power Systems Interference in electronic devices and how to mitigate the effects of them

In this article, some solutions are mentioned to avoid Electro Magnetic Interference (EMI) and also offer some circuits that used to omit EMI in power or input signals at-risk devices. Since the electronics equipment is installed beside the power systems in order to measure some parameters like current and voltage to improve their operation, it's necessary to protect them from installation area noise. Protection circuits are implemented in AMS-R3000 RTU device from Alborz Micro System co that satisfies IEC60870 standards. This device has been tested in Electrical and Power Industries Laboratories co (EPIL) and has successfully passed the type tests
