VDC TAKES ON VAC
  1. In the past
    1. Control devices , have required too much power
      1. With
        1. More emphasis on 24 Vdc as the control voltage of choice
          1. those
            1. include programmable logic controllers
    2. Technology advances
      1. appears the power transistors
        1. those
          1. help to reduce
            1. The issues of excessive dc voltage drop over long cable runs
              1. appear a new generation of
                1. Contactors
                  1. Starters
                    1. Control relays
                      1. Sensors
              2. The equipmnet
                1. Is focus on
                  1. The importance of personnel protection
                    1. using
                      1. remote switching and arc-venting switchgear
                      2. also
                        1. The codes and standards have changed significantly
                          1. Focus on
                            1. Reduce the potential of exposure to hazardous-touch voltages.
                2. The main objective is prevent the insecurity in the management of the electrical devices
                  1. And solve the issues that could happen with the changes
                    1. Also
                      1. Aspects
                        1. Design
                          1. Operational life
                            1. Reliability
                              1. Hardware
                                1. Costs
                                  1. Installation
