verband tussen lijnspanning, fase spanning, lijnstroom en fase stroom

The relationship between line voltage, phase voltage, line current, and phase current If you want to connect a 3-phase motor to a 3-phase network, knowledge of line and phase voltage is, in a sense, very important. Keep it simple: The motor's phase voltage is fundamental. The phase voltage is the voltage of the coil, the so-called coil voltage. This latter is limited during the motor's construction. The smallest voltage figure listed on the rating plate is the coil voltage (and therefore also the motor's phase voltage). If the coil voltage is too high, the current will also be too high, and the coil will inevitably burn out. Let me summarize: Main voltage: Delta: no neutral conductor, no indication of multiple voltage types. Line current is 1.73 x the phase current. Star: there is a (blue) neutral conductor, and two types of voltage are present. Line current = phase current 00:00 Introduction 00:50 Coil voltage on the motor rating plate 01:30 Mains: Delta Motor: Delta 02:20 Line voltage with Delta - Delta remains the same 02:40 Delta: Splitting line current into 2 x phase current 04:00 Mains: Delta Motor: Star 05:00 Motor in Star: Line voltage divides over the two phases of the motor 06:10 Motor in Star: Line current = phase current 07:00 Mains in Star, motor in Delta 07:50 Caution, the line voltage is 400V --- motor in Delta (line voltage = phase voltage) 08:15 Mains: Star Motor: Star 08:40 Motor in Star: Line voltage divides, line current = phase current
