-It's important to maintain the quality of the electrical and electronic devices (electrical household switches, sockets-outlet, .etc), since they pose danger to the users. These devices affect directly the national economy. Most of the international and national organizations including the Sudanese standard and metrology organization have paid so much concern to the electrical devices quality through stabling a lot of standard specifications to control its quality. Regarding the electrical household switches and sockets-outlet, all the standard specifications which have been established are required. The difficulties of simulating the normal operating test manually for the electrical household switches, and sockets come from the needs of perfectly performing the following tests: -Pregnancy current. -Electrical endurance. For electrical household switches (up to 15A, 250V) according to Sudanese standard SDS (3926/2007),and socket-outlet (up to12.5A,230V) according to Sudanese standard SDS (4829/2011), which required the on/off times for electrical switches to be approximately equal. So in this paper two separate devices are subjected to tests. The first one is for the electrical household switches and the second is for the sockets-outlet.
Remote surveillance monitoring have a wide variety of applications. Security is one of these applications .Different design technologies are implemented. This paper adopts the use of the programmable logic controller (PLC) as a device for performing the surveillance of the IP address wireless camera. Remote monitoring is performed through the
