transmitting electrical energy. isibly very different due to their Vmuch smaller size and cylindrical design, the new dry capacitors are al-ready making their mark in commercial use, for example in the DC links of high-voltage DC (HVDC) installations, where they stabilize DC transmission voltages ranging from 9 kV to 150 kV.
A look at how capacitors have developed from ‘wet to dry’ helps to explain the importance of the new technology. The smaller, the better. ABB’s new dry capacitor conventional capacitor of the same rating. Metalized capacitor film (left), showing typical segmentation. The size of the segments is about 1 cm2. The electrical interconnections in

ral part of the main switchboard.The rated voltage of the PMOD capacitor unit shall be at least equal to the service voltage of the network to which the capacitor is to be connected, account being taken of the influence of the
The new capacitors are less than the fluid-impregnated units they are designed to replace. opportunities. By combining eco-efficiency with environmental transmitting electrical energy.
1 . Should a breakdown occur, the metalized area and current gates around the fault vaporize to isolate it from the rest of the capacitor. This process is known as self-healing. Since only a very small part of the active area is de-stroyed, the loss of capacitance is negli-gible.
