WN, WNd - Voltage indicators

The devices can be used in any medium voltage indoor switchgear to determine the presence of voltage. They work with insulators having a built-in reactance or resistance voltage divider

WNd - Basic version voltage indicator

The basic version is characterised by certain features:

  • Meets the requirements of EN 62271-206:2011,
  • Compatible with reactance insulators from various manufacturers,
  • It is possible to change the sensitivity of the indicator depending on the parameters of the insulators. Acceptable output current level from isolators at 20....500µA,
  • It has an integrated design (has plug sockets and optical indicators),
  • Indicates the presence of voltage independently for each phase by means of LEDs,
  • The detection system does not require a separate power supply, the energy needed is received from the connected reactance isolators,
  • single-colour, transparent housing,
  • Intermediate protection rating IP 40.

WN - Increased tightness voltage indicator

The increased tightness version has, among other things, an increased IP protection degree.

  • Meets the requirements of EN 62271-206:2011,
  • Compatible with reactance insulators from various manufacturers,
  • It is possible to change the sensitivity of the indicator depending on the parameters of the insulators. Acceptable output currents from isolators of 20...500µA,
  • It has an integrated design (has plug sockets and optical indicators),
  • Indicates the presence of voltage independently for each phase by means of LEDs,
  • The detection system does not require a separate power supply, the energy needed is received from the connected reactance isolators,
  • Single-colour, transparent housing,
  • Interference protection rating IP 54.

WNf

Device used to indicate the phase relationship between the connection points of two systems indicating the presence of operating voltage. Installed in medium voltage switchgear, it is adapted for use with WNd, WN voltage indicators and PB switching interlock relays. It can also be used as an additional portable voltage indicator.
