Plate A is connected to the ground (at lower potential) so all the charge on it tend to go to the ground. Intermediate condition - Plate A is neutral, but Plate B has charge 60 x 10^-6 C, so it induces -60 x 10^-6 C charge on inner side(2) of plate A and 60 x 10^-6 C charge on outer side(1) of plate A.
For a switched capacitor bank, ground the jumper leads on the source side of the capacitor unit between the capacitor switch and the capacitor unit terminal. Before handling, short circuit the terminals of all capacitor units. Do not re-energize a capacitor that has possibly failed.
Abstract: In neutral grounding system, the neutral of the system or rotating system or transformer is connected to the ground. The neutral grounding is an important aspect of power system design because the performance of the system regarding short circuits, stability, protection, etc., is greatly affected by the condition of the neutral.
The following points highlight the four main methods used for grounding the neutral point of 3-phase electrical system. The methods are: 1. Reactance Grounding 2. Arc Suppression Coil Grounding (Or Resonant Grounding) 3. Voltage Transformer Grounding 4. Grounding Transformer. Method # 1. Reactance Grounding:
Open the fuse cutouts. DO NOT ground the capacitor bank immediately after the bank has been disconnected from the system. For capacitor banks with capacitor units containing discharge resistors designed to discharge the capacitor unit from peak rated voltage to less than 50 V in five minutes, allow five minutes before grounding.
In fact, it is beneficial because it establishes, in effect, a neutral point for the system; As a result, the phase conductors are stressed at only lineto- neutral voltage above ground. But problems can rise in ground fault conditions. A ground fault on one line results in full line-to-line voltage appearing throughout the system.
For capacitor banks with units containing discharge resistors designed to discharge the capacitor unit from peak rated voltage to less than 75 V in 10 minutes, allow 10 minutes before grounding. In the absence of design information, wait 10 minutes before grounding. Ground all parts after de-energization and before touching frames or terminals.

Get PriceThere are two main types of star connection: Grounded Star (Wye) In a grounded star or grounded wye connection, the neutral point of the bank is solidly grounded (earthed). This means that the neutral need not be insulated to the full system BIL level. Hence, some saving in cost can be realized by using this connection.
