  • TNTTIT Training kit (EL - 012)
  • Hard copy of the user manual
  • 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.
