Adaptation of the calculation of voltage and current from the raw data
The program allows the adaptation of the conversion of the raw data into the corresponding voltage and
current values. The default settings are already adapted to the EL3773 and do not absolutely have to be
changed for commissioning.
Only the transformation factor of the current transformer should be checked.
• All necessary settings for the calculation of the respective voltage and current values are made in the
MAIN. The presets correspond to the standard settings of the EL 3773
◦ rMaxVoltage specifies the maximum measuring voltage
◦ rMaxCurrent specifies the maximum measuring current
◦ iMaxRawValue specifies the raw value of the terminal at the maximum measuring voltage.
◦ The three variables rTransformerFactor specify the transformation factors of the current
transformers for the respective current channels
◦ Furthermore, offsets can be specified per channel. The inclusion of the offsets in the
calculation of the measured values takes place directly by means of adaptation of the
respective raw value.
