SAFETY DIAGNOSIS

Measurements on an HV isolation mechanism Experiment: Evaluation of interlock/pilot line

The technician will be able to measure the absence of voltage in the HV isolation mechanism. The technician will be able to experiment and reaffirm his knowledge of the pilot line or interlock loop by measuring the right signals before repair The technician will measure the active discharge of the capacitors, to reaffirm his knowledge and thus be able to identify if the HV disconnection is carried out correctly in a vehicle using oscilloscope and multimeter and identifying the signals The technician will diagnose a fault in the interlock loop system using oscilloscope and multimeter and identifying the signals The technician will measure the passive discharge of the capacitors, to reaffirm his knowledge and thus be able to identify if the HV disconnection is carried out correctly in a vehicle using oscilloscope and multimeter and identifying the signals The technician will be able to recognize a failure in the active discharge of the HV system and its consequences on the operation of the car using oscilloscope and multimeter and identifying the signals The technician will experiment with energy regeneration, gaining an understanding of the process using oscilloscope and multimeter and identifying the signals The technician will understand the particularities of the permanent magnet rotor by using oscilloscope and signals reading process The technician will understand the particularities of the rotor of a squirrel cage motor using oscilloscope and multimeter and identifying the signals The technician will experiment with controlling the speed and direction of rotation of the electric motor using oscilloscope and multimeter and identifying the signals The technician will diagnose faults in an electric motor and carry out its repair using oscilloscope and multimeter and identifying the signals The technician will understand what would happen if the phases of a motor change in the event of a short circuit or a bad repair. The technician will understand the characteristics of the Star connection The technician will understand the characteristics of the connection in Delta The technician will be able to diagnose a fault in the direction of rotation control of the electric motor
