Innkoblingspunkt

Innkoblingspunkt is a term used to describe the boundary or interface where a device, installation, or subsystem connects to a larger system, such as an electrical distribution network, a telecommunications network, or a data network. It denotes the point at which responsibility, control, and protection responsibilities transfer from one system to another and is central to planning, operation, and safety.

In the context of electrical power systems, innkoblingspunkt usually refers to the point where a customer’s installation meets the public electrical grid, often at the service entrance. This point is important for metering, protection coordination, and the ability to isolate the installation for maintenance or in case of faults. The term is closely related to the concept of the point of common coupling (PCC), which is used in grid-interconnection studies to specify the interconnection location and the sharing of electrical limits and protections.

For distributed generation, such as rooftop solar photovoltaic systems or small wind turbines, the innkoblingspunkt is the interconnection point to the grid. Regulations and standards typically define its location, required protective measures, and commissioning tests to ensure safety, anti-islanding protection, and proper operation within the broader network.

In telecommunications and data networks, the innkoblingspunkt can refer to the demarcation point between the service provider’s network and the customer’s premises equipment. This demarcation defines where the provider’s responsibilities end and the customer’s responsibilities begin, and it is often a focal point for service assurance and fault attribution.

Overall, the innkoblingspunkt is a practical and regulatory concept that marks where systems are joined, with implications for safety, metering, protection, and accountability.
