Fault current, A Calculate fault details at a location given the apparent power (VA) current and power factor. Complex (apparent) power, Volt-amp. Calculate fault details at a location given the fault impedance and power factor. Source impedance magnitude, Ω. Normally used for fault calculations. Calculate full cable fault details, including source fault details, destination fault details and cable fault ratings. Cable detailsID [sourceID > cableLibraryID > cableDetialID] List of allowable single core cable configurations, (ID and description). Used with other calls (for example, sustained current capacity of single core cables). Calculation of the dc resistance for a cable or conductor, using basic electrical engineering formulae. For cables, you may be better using the API by cableDetailID, which will first try to set the resistance in accordance with cable standards. Conductor material ID Calculation of the dc resistance for a cable or conductor. This call will first try to match the cable details with resistance values given in IEC 60228, falling back on standard electrical formulae if no match is found. cableDetailID (use cable library calls to find appropriate ID) Calculation of the positive sequence impedance [Z1] for single core cables.. cableDetailID (use cable library calls to find appropriate ID) Calculation of the positive sequence impedance [Z1] for multicore cables.. cableDetailID (use cable library calls to find appropriate ID) Calculation of the zero sequence impedance [Z0] for single core cables.. cableDetailID (use cable library calls to find appropriate ID) Calculation of the zero sequence impedance [Z0] for multicore cables.. cableDetailID (use cable library calls to find appropriate ID) Calculate d.c. resistance of a conductor at 20°C Electrical resistivity of conductor or material at 20°C, Ω.m Calculate d.c. resistance of a conductor at T°C Electrical resistivity of conductor or material at 20°C, Ω.m Adjust the d.c. resistance at a certain temperature to that at a new temperature.

Calculates electrical power, given the voltage, phases configuration, efficient (if a device), current and power factor. Voltage, V. For a.c. 3-ph line-line expected, for 1-ph line-neutral expected. Calculates the power loss in a cable, taking into consideration the phase (i.e. d.c., single phase or three phase). Resistance of a cable (single conductor) or circuit element, Ω Calculates electrical power, given the impedance (resistance and reactance) and current (magnitude and power factor). Calculation is valid for both a.c. and d.c. circuits. Returned real value is power, imaginary reactive power and magnitude VA. Resistance of a cable (single conductor) or circuit element, Ω Provide a complex representation of the voltage given it's magnitude and phase angle. Note: normally take the voltage as reference (phase angle = 0), unless carrying out system calculations in which case use the actual phase angle. Magnitude of the voltage, V Calculates a voltage drop across a cable or circuit element. Voltage drop calculated in accordance with CENELEC technical report CLC/TR 50480. This is intended for calculation of voltage drop across cables, where conductor impedance is known. Magnitude of the voltage, V Gets a list of phase IDs and associated description. PhaseID is used in many calls to differentiate between systems (i.e. single phase or three phase). Calculates a voltage drop across a cable or circuit element. Voltage drop calculated in accordance with I*Z. For d.c. set the power factor = 1.
