OBJECTIVES

Centre for Electric Transportation (CET) has been established at Bhopal with the assistance from United Nations Development Programme (UNDP). The centre is envisaged to act as a focal point for systems oriented research in the field of electric transportation. CET has capability for analysis and testing of rail vehicles for their performance, reliability and energy efficiency. CET can also provide assistance in development and introduction of urban mass transit systems.

FACILITIES

• Provision for different types of power supply prevalent in Indian Railways for powering locomotives, EMU, MEMU, and metro. They include 0-750V 3x800 amp DC power supply, 0-1500V 2x800 amp DC power supply, 25 KV single phase 50 Hz 4 MVA AC power supply, 800 KVA auto transformer with tapping of 1150/100/750 V 3 3 Φ 50 Hz AC supply and MG set which provides current up to 180 amp from 0-230 volts.
• DC motor generator set which can be used as prime mover with power up to 750 KW and 1500 rpm and as for regenerative loading up to 1000 amp, 750 volts of rotating machines, up to 1050 rpm, and other static equipment.
• Load bank of 3 nos. resistance bank of 5 ohms (reconfigurable 0.25 ohms), 500amp and 16 nos. resistance banks of 1.8 ohms, 50 amp.
• Vibration testing facility for conducting vibration testing of traction equipment, consisting of a 250 KN servo hydraulic actuator powered by 210 bar hydraulic power supply. The actuator can provide a maximum displacement of +/- 75 mm over a frequency range of 0.01-1100Hz.
• Type testing facility for AC motors for sub-urban trains which can be utilized for conducting various tests called in IEC 60349-2 for type testing of inverter fed traction motors up to the ratings of voltage of 1400 V 3-Ф AC supply, current of 400 amp and frequency up to 200 Hz.
