Three Phase Transmission Line Symmetrical & Unsymmetrical Fault Trainer Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12943
Indian Lab Suppliers supplies the Three Phase Transmission Line Symmetrical & Unsymmetrical Fault Trainer (Product ID: 12943) as part of its electronics engineering lab equipment range. It is a three-phase line model for creating and measuring symmetrical and unsymmetrical faults.
Quick Answer
A 1 kVA three-phase step-down transformer (415 V to 240 V line) feeds the line model, and faults are switched in at an operating voltage of 30 V with a fault current of 5 A. Students apply single line to ground, line to line and double line to ground faults (unsymmetrical), plus L-L-L and L-L-L-G faults (symmetrical), and compare the fault currents and sequence behaviour on the panel voltmeter and ammeter. Test terminals let the waveforms be viewed on an oscilloscope, and a selector switches the display between line and phase voltage.
Key Features
6 fault experiments: L-G on a single-phase line; L-G, L-L, L-L-G, L-L-L and L-L-L-G on a three-phase line · Line and phase voltage selection · Test terminals for waveform analysis · Panel parts include MCB, selector switch, meters, transformer, indicating lamps and fuses

Where This Is Used
Used in power system protection and fault-analysis practicals. The primary side runs at 415 V three phase, so keep the unit earthed and make fault connections with the supply off.
