Protection and control platform (By relay application)

Capacitor Bank Protection

The ALP relay enhances the protection coverage of your capacitor banks with the help of an Impedance-Based element (21C). This element has a better sensivity to detect faults and provides valuable information to better target the maintenance of capacitor banks.

  • Applicable to fuseless, fused, grounded and ungrounded systems
  • Better localization of the shorted section, reducing maintenance time
  • Better availability of the bank because the protection discriminates between capacitor failures in one string versus capacitor failures spread through the bank
  • Protection not affected by bus voltage variations
  • Immune to temperature variations and to temperature gradients in the bank due to an advanced temperature compensation algorithm (patent-pending)

Hardware configurations

  • ALP-2000: Combination of twelve (12) current and voltage inputs, six (6) digital inputs, four (4) relay outputs, two (2) high-speed power outputs, up to four (4) fiber Ethernet ports
