Product Code : SCL-EELE-12853
Indian Lab Suppliers supplies the Power Transmission Line Trainer (Product ID: 12853) as part of its electronics engineering lab equipment range. It is a panel trainer that models a 400 kV, 1 MVA three-phase transmission line scaled down 1000:1 for line, compensation and fault studies.
Quick Answer
The line panel builds medium or long line models (125 km or 250 km) in π or T form from six each of 10 Ω / 600 W resistors, 0.15 H / 5 A inductors and 2.2 µF / 630 V capacitors. Supply comes through a DOL starter panel and a three-phase dimmer (415 V in, 0-470 V, 6 A out), and two bidirectional multifunction meters with RS-485 Modbus read sending- and receiving-end power. A VAR compensation panel (2-15 µF, three per value) and an RLC load panel with resistor, inductor and capacitor taps, including a 262 Ω surge-impedance-load tap, complete the set. Students study the Ferranti effect, ABCD constants, regulation and efficiency, power circle diagrams, per-unit values, symmetrical and unsymmetrical faults and LG faults with and without a Petersen coil, and solve two-bus power flow by Newton-Raphson, Gauss-Seidel or fast decoupled methods. It runs from 415 V three-phase, so wiring must be done with supplies off and under qualified supervision.
