A fuse includes an integrated measuring function. In an embodiment, the fuse includes a fuse housing including a first receiving space delimited by a pressure body and a second receiving space spatially separated from the first receiving space. A fusible conductor is mounted in the first receiving space and a measuring device is accommodated and mounted in the second receiving space. The measuring device has a current transformer and an electronic assembly, electrically conductively connected to the current transformer. Viewed in a direction of longitudinal extent, a height of the current transformer essentially corresponds to a height of the second receiving space. With the aid of the measuring device, it is possible to determine the electric current flowing through the fuse in the immediate vicinity of the fuse. Energy required is generated from the primary current of the fuse by electromagnetic induction, meaning no external power source is required.

A fuse box mounted on a liquid-filled transformer is disclosed. The fuse box may include one or more fuse link assemblies securing one or more fuses within a base fuse box, a fuse holder coupling the one or more fuse link assemblies within the base fuse box, wherein the one or more fuse link assemblies are pulled-up from the fuse holder by hand to remove the one or more fuse link assemblies from the base fuse box. The fuse box may include a retaining ring to fasten the fuse holder to the one or more fuse link assemblies. The fuse box may include a method for servicing a fuse box on a liquid-filled transformer.

An electro-mechanical disconnector mounted between an HV overhead power line conductor and a voltage transformer, mounted on a support of the support power line of HV overhead power line conductors. The electro-mechanical disconnector comprises an isolating element and a sacrificial element arranged in series with each other. The sacrificial element is made of a material capable of melting upon the passage of a fault current, and the sectioning element is capable of moving to an electrically insulating distance from the conductor following the melting of the element.

In example implementations, a printhead die is provided. The printhead die includes a substrate, a chamber layer formed on the substrate, a plurality of printing fluid ejection chambers coupled to opposite sides of the chamber layer and along a length of the chamber layer, and a top hat layer formed on the chamber layer and the plurality of printing fluid ejection chambers. The chamber layer includes a void to store printing fluid. The top hat layer includes an initial unsupported top hat layer portion over the void, wherein the initial unsupported top hat layer portion comprises a first end that is narrower than a second end.

A current limiting fuse assembly includes a current limiting fuse having a longitudinal axis, and a shielding arrangement configured to electrically and mechanically shield the current limiting fuse. The shielding arrangement includes a first part and a second part. The first part includes a cylindrical portion extending along a first axis between a first end and a second end, and a flange portion provided at the second end. The second part includes a cylindrical portion extending along a second axis between a first end and a second end, and a flange portion provided at the second end. The second part is positioned and oriented relative to the first part such that the second end of the second part faces the second end of the first part. The second end of the second part is arranged at a distance from the second end of the first part.
