Product Code : SCL-EELE-12859
Indian Lab Suppliers supplies the Transformer Trainer with 3 Ph. Variac (Product ID: 12859) as part of its electronics engineering lab equipment range. It is a panel-based transformer trainer, offered in 300 VA and 1 kVA/3 kVA models, for more than 25 single- and three-phase transformer experiments.
Quick Answer
Panels on an aluminium profile frame bring every connection to 4 mm shrouded sockets: a 415 V DOL starter, three bidirectional three-phase meters, a FWD-OFF-REV switch, a single-phase input panel and a 3 × 100 W lamp load. The 300 VA model adds a 500 V voltmeter, a 2/6 A ammeter, a milliohm (V-I) and rectifier-capacitor panel and AC and DC resistor loads; the 3 kVA model adds a 12 A current-injecting transformer, DC meters, a three-phase dimmer (415 V in, 0-470 V, 6 A out) and 1 kW single- and three-phase resistor loads. Experiments include insulation, turns-ratio and polarity checks, open- and short-circuit tests, Sumpner’s back-to-back test, temperature rise, DC winding resistance, parallel operation, Scott connection, vector groups, tertiary-winding harmonic suppression, zero-sequence reactance and the equivalent circuit. The model to be supplied and the variac arrangement should be confirmed at quotation; work at 415 V only under supervision.
