The aim of this project is the improve the design and programming of Emergency Inverter Bench Test Equipment (EI-BTE). The EI-BTE wil be used to verify the funcionality of the emergency inverter of the LIRR/MNR M7 HVAC. The HVAC is the Heating Ventilation and Air Conditioning system of M7 electric train (Long Island Rail Road/Metro-North Rail Road, USA). Typically, the BTE will be installed in a dedicated repair room and user by test and repair operators.
The EI-BTE is composed of the following elements: an industrial 19' PC with A/D PCI card, 3 powermeters connected by RS-485, a programmable power suply, an oscilloscope, etc.
The EI-BTE software performs automatically all the emergency inverter tests. The operator needs only to plug in a emergency inverter. The test determines and indicates the health of the emergency inverter, without further intervention by the operator. If the emergency inverter is defective, the EI-BTE guides the operator to identify the fault component.
