  • Page 11: Safety

    2. Safety 2. 1 Intended use The voltage and frequency monitoring relay VMD460-NA is used for system and network protection (NS protection) of CHPs, wind, hydroelectric and pho- tovoltaic systems feeding power into the grid. If inadmissible voltage and frequency values occur on the supply side, the VMD460-NA has the task of disconnecting the power generation system from the distribution network by means of a coupling switch.

  • Page 12: General Safety Instructions

    Safety 2. 3 General safety instructions Bender devices are designed and built in accordance with the state of the art and accepted rules in respect of technical safety. However, the use of such de- vices may introduce risks to the life and limb of the user or third parties and/ or result in damage to Bender devices or other property.

  • Page 18: Passive Islanding Detection (Df/Dt)

    Function 3.2.10 Passive islanding detection (df/dt) The VMD460-NA uses a passive method for islanding detection (three-phase voltage and frequency monitoring). df/dt The monitoring of the rate of change of frequency "ROCOF" (df/dt) is an islanding detection function. If a section of the network is disconnected by the energy provider, it may hap- pen that the power generation systems located in this section unintentionally feed this section of the network.
