    In case postive to ground showing +70v and negative to ground - 40 v . What that means , i observed such type of volatge in many of the substations

      it look like negative earth fault is there or there should be problem in mid point earthing system thank you.

    Hi sir, thanks for the video. this is midpoints/center point earthing.
    1.what is the another earthing type? positive connection to earth or negative connect to earth.
    2. i notice that the most substation using this type of connection. while for the power plant with alot of instrumentation using negative connection to earth. im wondering why.
    3. i think this is the best connection to protect instrumentation/plc/ vfd
    thanks in advance for your reply.

    Thanks dear ,very useful explanation,also one doubt this mid point normally taken from battery or in charger in substation?(because both are conected in Parallel)

      The shown diagram shows solid earthing of the mid point of the battery bank. If the mid point is earthed solidly, there is still path for half the fault current that would have been present if the battery set's -ve was earthed.
      The correct way to earth the battery system is:
      Earth the mid point of the battery bank via a high resistance in the charger. This way, the voltage will be halved. Also, the return fault current if any, will have to overcome the high resistance in the return path to the mid point of the battery bank which earthed as a reference point.

    Could you explain the effect of DC positive or negative eath fault on the trip circuit ? And how can that cause malfunction for protection relays ?

    Dear sir
    In our substation DC grounding is not done, what is the advantage and disadvantage of this.

      your asking about DC battery leakage sir.

    For a full battery bank earth system of 30v DC system the phase to earth voltage is 30v,but the phase to earth voltage will be zero volts.

      Positive to earth or negative to earth

      @erfan_muhammad 2 роки тому

      i dont understand the question.. do you mean
      +ve to earth = 30vdc
      -ve to earth = 0vdc. interested to understand

    the metal scale is not connected to ground.. then how it is acting like earthing, someone pls explain..?????
