Competency-based teacher training using didactic boards in the Electrical Technology course
group of students where the use of the didactic boards, will be a main
part of this result.
An electrical panel is a closed metallic box that contains the
connection, maneuvering, command, measurement, protection, alarm
and signaling devices, which fulfill different functions in a single or
three-phase electrical system. The elaboration or construction of an
electrical panel, must meet design criteria and various regulations
NEC, IEEE, NATSIM that allow its correct operation once energized,
ensuring the safety of operators and facilities in which they are
located.(González Lopera, 2019).
Controlling is a paradigm of the human being, likewise cover the gap
of what was studied in the classroom with the industry should be a
priority (modernize), therefore it is mandatory to design control
boards of alternating current induction motors, where the student can
prove to himself that he can do it, in this learning as a first step we
describe the principle of the induction machine, the working
conditions with changes in voltage, frequency and phase for
operation. Then next explain the purpose of building the board for the
practice of motor control, also how the design of the board was made
so that it is didactic to project learning to future generations. The
scope that has project is to try to maximize the number of motor
control practices using measurement equipment connected
applications, explaining and describing the parameters to be
measured, electrical connections, as well as build the guide (González
Lopera, 2019)We always associate, that electrical panels are metal
structures, in which the connection-disconnection, control,
protection, measurement, signaling and distribution devices are
concentrated; all these devices allow an electrical installation to
operate safely (González Lopera, 2019).
Every electrical system is made up of a type of energy, conductors,
and a receiver that changes the electrical energy into light (lamps),
movement (motors) and heat (stoves). For the transformation to
occur, it is necessary that current flows through the system, this must
be composed of conductive elements, connected to a source of
voltage or voltage, the devices that allow to open, close or control
systems are called switches or keys. The devices of an electrical
system are said to be in series when they are placed one after the other
so that the electrons passing through the first device of the system and
then through the other devices. The intensity of the current is the same
at all points of the system, characteristic of series circuits (voltage
control), we can also connect the elements next to each other so that
