A distribution trans- former is a static device constructed with two or more windings used to transfer alternating- current electric power by electromagnetic induction from one circuit to another at the same frequency but with different values of voltage and current. Figure 15.1 shows distribution transformers in stock at an electric utility company ser- vice building. The distribution transformers available for use for various applications, as shown, include pole-type (Figs. 15.2 and 15.3), pad-mounted (Fig. 15.4), vault or network type (Fig. 15.5), and submersible (Fig. 15.6). The distribution transformer in Fig. 15.2 is self-protected. It is equipped with a lightning arrester, a weak-link or protective-link expulsion-type fuse (installed under oil in the trans- former tank), a secondary circuit breaker, and a warning light. The transformer primary bushing conductor is connected to one phase of the three-phase primary circuit through a partial-range current-limiting fuse. The transformer tank is grounded and connected to the FIGURE 15.1 Electric utility distribution storage yard. Forklift trucks are used to load transformers on line trucks.

These power cables could be alternating for smart grids, vehicular communications, internet of things current (AC) or direct current (DC) power lines and the signals and data network access has recently gained ample interest in of PLC transceivers are subsequently coupled to them via a industry and academia. Due to the characteristics of electric power grids and regulatory constraints, the effectiveness of coupling circuit. In the case of power lines used to transmit coupling between the power line and PLC transceivers has AC power, the coupling circuit has also to filter out the AC become a very important issue. Coupling devices used to inject or mains signal. On the other hand, the coupling circuit simply extract data communication signals into or from power lines are has to block the DC mains voltage of the DC electric power very important components of a PLC system. There is, however, grids. an obvious gap in the literature for a detailed review of existing PLC couplers. In this paper, we present a comprehensive review During the late 1970s and early 1980s, new investigations of couplers, which are required for narrowband and broadband to characterize electric power grids as a medium for data PLC transceivers. Prevailing issues that protract the design of communication showed a higher potential in the range of couplers and consequently subtended the inventions of different frequencies between 5 kHz and 500 kHz [2].
