All legal rules have to be ob- served and technical standards have to be met. Before connecting the device check that all connecting leads are de-energized and that current transformers are bypassed.

  • Page 6: Voltage Measuring

    Technical Documentation Rev. 01 Power Factor Regulator BLR-Q(U) Page 6 of 39 1.3 Voltage measuring Terminals Um1 and Um2 are used for voltage measuring. Effective range is 50V to 530V AC and 45Hz to 65Hz. Voltage measuring is necessary for calculation of control deviation and capacitors sizes for reactive power regulation as well as for monitoring and protecting capacitors against over- and undervoltage and THD U and for showing different measuring values.
