How much do you lose along the line?
Synusoidal AC line, single-phase or three-phase balanced, inductive load. Insert resistance and rectifier for conductor from the cable manufacturer, to the operating temperature. Not applicable to the PWM output of a Drives, in point or to unbalanced loads.
Formula and source
ΔU = k × I × L/1000 × (R × cos φ + X × √(1 − cos2 φ)); k = 2 in monophase, √3 in triphase. Percentage = 100 × ΔU / U. It is the only route: add the fall upstream for the total. No universal regulatory threshold is applied.
Schneider Electric · Electrical Installation Practical guidesProtection and line are consistent?
Check of three numerical conditions for a switch that also protects from overload. Do not choose the compressor's curve or magnetothermic. For separate overload protection, fuse or Drives, use the manufacturer's specific coordination.
Please note: start-up and time-current curve, coordination with contact and overload, passing energy, interruption times, selectivity, differential protection where required and OEM requirements. Break data related to correct voltage and device standard.
