FEATURES The db-tech, DB-SM-24 Transformer Trainer is designed to demonstrate the characteristics of 1Phase and 3phase transformer. The students can measure various parameters of a transformer like resistance, saturation, curve, impedance, polarity etc. They can also experiment load and no-load characteristics of a transformer and measure the performance of it. It is a self contains module and require no additional accessories for operation.   SPECIFICATIONS Specification ■ 3Phase 220V / 50/60Hz (380V / 415V - Selective) ■ Single Phase Transformer - 400VA - Primary : 0 / 110 / 220 / 380V - Secondary : 0 / 110 / 220 / 380V ■ Main Power Switch (MCCB) ■ 3 Phase Variable Supply ■ AC Ampere-meter ■ AC Volt Meter ■ 3 Phase Digital Watt Meter (Optional) ■ Power Lamp ■ Load Connection Block ■ Load Main Switch (MCCB) ■ Load Toggle Switch Experiment ■ Measuring Coil Resistance of Transformer ■ Saturation Curve and Voltage Ratio of 1Phase Transformer ■ Impedance of Transformer ■ Current Ratio and Impedance of Transformer ■ Voltage Regulation Curve of Transformer ■ Polarity of Transformer ■ No-Load & Load Experiment of a 1Phase Transformer ■ Short Experiment of a 1Phase & 3Phase Transformer ■ Parallel Operation of a 1Phase Transformer ■ Three Phase Connection of a 1Phase Transformer ■ V Connection Practice of a 1Phase Transformer ■ No-Load & Load Experiment of a 3Phase Transformer Accessory ■ Experiment Manual: 1 Copy ■ Test Lead (Banana Plug): 1 Unit ■ Power Cable: 1 EA ■ Dust Cover: 1 EA Option ■ 3 Phase Digital Watt Meter (DB-SM-24P) - Watt Meter (2EA)
