SpletPCB-containing capacitors have been found in electric locomotives. In coalmines, capacitors are often in wheel or skid-mounted power centers as shown in Figure 3. The PCB regulations require these items be identified by PCB marks (or labels) if they contain 500 ppm (0.05%) or more PCBs and they are termed PCB transformers or capacitors.
