Dc control supply earthing system
110v dc system how we getting 55v positive to earth or negative to earth.
normally we get 110v between + to- .then how getting 55v respect to earth
Why we use DC supply in Substation or Switch gear?
What Earthing system are mostly using in Substation or Switch Gear?
What is the application of Mid-Point Earthing ?

Many thanks for the video. It cleared many things up! all the best

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.

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

@baranitech1026 6 месяцев назад

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

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 ?

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)

@rajeshtk1246 5 лет назад

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.
