A holding device includes a Rogowski coil, where the Rogowski coil includes a line portion wound into a coil. The holding device further includes a housing part into which the Rogowski coil is connected. A fastening part is configured to be releasebly connected to the housing part and is further configured to be attached to a current-conducting means formed for conducting a current.

Holding device for a rogowski coil

The subject matter herein pertains to a current transformer, comprising a secondary coil, connection contacts for establishing electrically conductive contact with the secondary coil from the outside, and a housing having a housing body and a housing head, wherein the secondary coil is accommodated in the housing body and/or is attached to the housing body, and the connection contacts of the secondary coil are provided on the housing head. According to one implementation, a connecting mechanism is provided, by means of which the housing head and the connection contacts can be mechanically or electrically conductively detachably connected to the housing body and to the secondary coil. A current transformer is therefore provided, which is cost-effective to produce and is flexible in terms of the use thereof.

Electrical measuring device

A generator junction box for a photovoltaic generator is presented, which has a junction box housing with a back wall and a surrounding side wall, and input modules, each with an integrated quick connector for connecting a generator string line to the associated input module, wherein the input modules are situated directly against the surrounding side wall of the junction box housing in such a way that it is possible to connect the string lines directly to the quick connector of the associated input module from the outside.

Generator connection box for photovoltaic installations

The invention relates to a radio network comprising a plurality of first clients which can communicate with one another by means of radio waves, wherein the first clients have at least one input unit for the input of data and/or at least one output unit for the output of data, wherein a first reference can be adjusted on one input unit and a second reference can be adjusted on one output unit, wherein the radio network is configured such that the incoming data to the input unit is communicated to the one or more output units the second reference thereof corresponding with the first reference adjusted on the input unit.

Wireless network

A monitoring device for an ungrounded electric network of a photovoltaic system. The monitoring device includes a short circuit measuring circuit having a first electric measuring circuit conductor connecting a first electric pole of the photovoltaic system with a reference point by means of at least one protective component, and second electric measuring circuit conductor for connecting a second electric pole of the photovoltaic system with ground be means of at least one protective component. A first component is connected between one of the measuring circuit conductors and ground, and a measuring device for measuring an electric parameter of the first component, wherein a non-zero value of the parameter and/or a change of the value of the parameter indicate an electric fault between the photovoltaic system and ground.
