    Abstract: A varistor, or voltage-limiting composition has a polymer matrix and a particulate filler containing a partially conductive material applied to an electrically non-conductive carrier material. The carrier material has a lower density than the partially conductive material, so that the settling rate of the filler in the polymer matrix is reduced. The voltage-limiting composition can therefore also be used as a lacquer or for prepreg materials. A body which acts as a varistor may be produced using a composition of this kind by a method that includes annealing. The varistor may be used for surge arresters, in particular in medium-voltage systems, low-voltage systems, cable connections and cable fasteners.

    Abstract: A variable impedance composition according to this aspect of the present invention comprises a conductive powder in an amount from 10% to 30% of the weight of the variable impedance composition, a semi-conductive power in an amount from 30% to 90% of the weight of the variable impedance composition, and an insulation adhesive in an amount from 3% to 50% of the weight of the variable impedance composition. According to one embodiment of the present invention, the variable impedance material presents a high resistance at a low applied voltage and a low resistance at a high applied voltage. As the variable impedance material is positioned in a gap between two conductors of an over-voltage protection device, the over-voltage protection device as a whole presents a high resistance to a low voltage applied across the gap and a low resistance to a high voltage applied across the gap.

    Abstract: An overvoltage device that is formed from a MOV device that is coupled in parallel with a spark gap. This device is coupled upstream from electronic components to protect these components from damage. For example, in one embodiment, the overvoltage device is coupled to a fault circuit interrupter such as a GFCI, across the phase and neutral lines to protect components of the GFCI from an overvoltage condition. In one embodiment the overvoltage device is formed as an MOV physically coupled to a spark gap wherein the MOV and the spark gap are electrically coupled across the phase line and the neutral line in parallel.

    Abstract: A method to increase capacity of a passive element to accommodate inrush current is mounting a metal pad in a circuit to evenly distribute the current over a greater area so heating caused by the current to be distributed over a greater area. The passive element has two electrodes attached on a ceramic disc and connecting respectively to two terminals. The metal pad is mounted between one of the electrodes and the corresponding terminal to increase the contact surface between the electrode and the terminal. Then the current passing from the metal pad to the electrode is distributed evenly. Therefore, when the inrush current passes through the circuit, the electrode will not be melted easily to ensure the passive element working normally most of the time.

    Abstract: The resistor is designed in the form of a column and has a cylindrical resistor body which is arranged between two planar electrodes, aligned parallel, and is made of a ceramic material. The resistor is preferably a varistor on a metal-oxide base, and is then used as a voltage-limiting element in an overvoltage suppressor. The strength of the ceramic material and the length of the resistor are chosen to be as great as possible. However, the length of the resistor is at most sufficiently large that damage to the ceramic resistor body caused by thermally produced pressure waves is avoided when the resistor is loaded in an electrical field of given magnitude with at least one highly energetic current pulse of defined amplitude, form and duration.
