  • TNTTIT Training kit (EL - 012)
  • Hard copy of the user manual
  • Electrical installations training frame (EL - 301)

This training kit contains multiple module which can be mixed and matched when combined with the electrical installation frame. Upon connecting these modules, trainee can perform earthing experiments allowing them to gain more practical knowledge regarding this field.

                                     
  • The training kit consists of up to 5 modules which can be mixed and matched to carryout various earthing experiments.
  • All of the modules contain power supply terminals and earthing terminals to receive power from the main frame.
  • Using this kit, trainees will acquire knowledge regarding electrical wiring and earthing circuit designing and forming.
  • Three phase transformer module is supplied This module is configured as delta-star step-down transformer used in distribution station to be able to simulate earthing methods TN, TT, IT.
  • Resistor module is assembled as contactor that operate as zero-ohm resistor when the button with red led light is pushed. Module need to be energized on CL, and CN with 220 VAC.
  • Pole circuit breaker module consists of four-pole Miniature Circuit Breaker (MCB), and four-pole Residual Current Circuit Breaker (RCCB). RCCB input terminals are internally connected to the output terminals of MCB this means two breakers are connected in a cascaded manner.
  • Three-phase power meter module measures all parameters of an electrical network, calculate the consumption values and display these on its LCD screen. Measured parameters will be recorded in real-time thanks to internal flash memory and Real Time Clock chip.
  • Insulation monitor module is also included in this kit allowing for further experimentation.
  • Another pole circuit breaker module is provided allowing the trainees to provide protection over the implemented circuits.
  • The modules are well protected in a provided kit to protect against wear and deterioration.
