摘要： A surge protection device and method for protecting an electric system against overvoltage occurrences, the surge protection device includes a first surge arrester and a second or additional surge arresters connected electrically in parallel, the first surge arrester and the second surge arrester are configured to be disconnected from the electric system in a sequential predetermined order as each one is overloaded and becomes unusable as a surge arrester, remaining the electric system protected until the last one is disconnected. Various combination of externally gapped, internally gapped, and ungapped surge arresters are used to create the uninterruptable protection in the electric system.

摘要： A system or method for monitoring an electric power lightning arrester including an arrester current sensor providing an arrester current measurement, and an arrester voltage sensor providing an arrester voltage measurement. The system detects a switching signature based on the arrester current measurement or the arrester voltage measurement distinguished from background noise and lightning signatures and computes a measured arrester impedance based on the arrester current and arrester voltage measurements. The system then compares the measured arrester impedance to a nominal or historical arrester impedance, determines that the arrester is faltering based on the comparison of the measured arrester impedance to the nominal or historical arrester impedance, and places an order for replacement of the arrester based on the determination that the arrester is faltering. The system operator then replaces the arrester during a fair-weather, typically off-peak period to avoid failure of the arrester during a lightning strike.

摘要： A surge protection device has a housing that is formed from a first lateral portion, a middle portion, and a second lateral portion that are connected together with a plurality of fasteners. The surge protection device includes an electronic apparatus having a neutral wire and further includes a housing that advantageously includes a strain relief that causes the neutral wire to frictionally engage the housing with sufficient friction to resist a predetermined tension applied to the free end or other portion of the neutral wire at the exterior of the housing from damaging an electrical connection between the neutral wire and a circuit board within an interior region of the surge protection device.

摘要： A surge protection device has at least one disconnecting device (34), at least one actuating device (36), an indicating device (40), and a shaft (38) mounted for rotation between at least a first position and a second position, the at least one actuating device (36) being variable between a first position and a second position. The shaft (38), the indicating device (40) and the actuating device (36) are formed in such a way and the actuating device (36), when in the first position, is fastened to the at least one disconnecting device (34) so as to be preloaded such that when the disconnecting device (34) is triggered, the actuating device (36) is released and triggers the indicating device (40) by means of the shaft (38). Further, a modular surge protection system is described.

摘要： The present disclosure is directed to a method of producing a surge arrestor module, comprising the acts of (i) providing a plurality of MOV blocks arranged in a stack, (ii) applying an epoxy-reinforced structural layer to an outer surface of the stack, (iii) after the applying, inserting the stack into a flexible bladder, and (iv) curing the epoxy-reinforced structural layer with elevated temperatures while the flexible bladder applies radially aligned pressure to the stack and a tool applies axially aligned pressure to the stack. The present disclosure also includes an apparatus for performing the methods described herein. The apparatus includes an outer case structure and a flexible bladder that fits within the outer case structure. A hollow inner region of the outer case structure is pressurized to force the flexible bladder against the surge arrestor module as the surge arrestor module is curing.

摘要： A support arrangement for an electrical protection assembly for connection between an electrical power supply line and electrical equipment is provided. The support arrangement comprises a first insulator body and a second insulator body extending at right angles to the first insulator body, wherein the first and second insulator bodies are integrally formed into a unitary body. In an embodiment, the second insulator body extends from a lower end of the first insulator body, so as to define a unitary L-shaped support arrangement. In one version, the support arrangement comprises an L-shaped inner support frame around which the first and second insulator bodies are molded. The L-shaped inner support frame comprises a T-shaped metal connector having a first end from which a first fibre glass support arm extends, around which the first insulator body is molded, and a second end from which a second fibre glass support arm extends, around which the second insulator body is molded.
