Abstract: A pole part of a switchgear assembly having a vacuum interrupter chamber is provided. To ensure that heat is dissipated to the exterior for convection, a thermally conductive heat transmission element in the form of a cylindrical casing is provided between the vacuum interrupter chamber, a contact holder and an encapsulation casing. An inner surface of the heat transmission element rests on the vacuum interrupter chamber and the contact holder, and an outer surface of the heat transmission element rests on an inner surface of the encapsulation casing inner surface. The heat transmission element can be produced from a thermally conductive plastic using an injection-molding or molding-compound production process. The heat transmission element can be connected to the pole part through openings. The heat transmission element can be arranged before the encapsulation of with an encapsulation compound, and be cast in the encapsulation casing.

Abstract: The invention concerns a method and computer program product for determining the direction of fault in an electrical power system as well as to a fault handling device. In the fault handling device the voltage at a measurement node of the power system is measured, the phase (φPF) of this voltage (VPF) before a fault is stored, the phase (φF) of this voltage (VF) at the end of a time interval (TI) following directly after a detected fault is determined, a phase offset (φO) is determined as the difference between the phase (φPF) of the measured voltage (VPF) before the fault and the phase (φF) of the measured voltage (VF) at the end of the time interval (TI) and the phase (φF) of the measured voltage (VF) after the detection of the fault is adjusted with the phase offset (φO). Thereafter the adjusted measured voltage is used in determining the direction of fault in relation to the measurement node.

Abstract: A method and an apparatus for calculating the separation time of the arcing contacts of a high-voltage switchgear which is operatively coupled to a synchronous switching device and to an auxiliary switch having auxiliary contacts operatively connected to the arcing contacts. During execution of a predefined test condition the separation time of the arcing contacts and of the auxiliary contacts is measured. The time delay between the measured separation time of the arcing contacts and of the auxiliary contacts is calculated. Upon separation of the arcing contacts under an operating condition other than the predefined test condition, the separation time of the auxiliary contacts is measured. Then, the separation time of the arcing contacts is calculated as the difference between the separation time of the auxiliary contacts measured during the operating condition other than the predefined test condition and the calculated time delay.
