ontvangststroom

Ontvangststroom is a term used in electrical engineering and installation practice to describe the electrical current that flows into a device, installation or system from a power source at the point of connection. It represents the input current drawn from the grid or other supply, before internal distribution and conversion take place. Depending on the context, it may be described per phase in single‑phase or three‑phase networks; the value is typically the root-mean-square (RMS) current.

In practice, ontvangststroom is measured and monitored to ensure safety and proper functioning of electrical systems. It is commonly determined with current sensors or meters installed on the incoming conductors, and it is used to size cables, protective devices, and switchgear. Protective relays and circuit breakers are configured to accommodate the expected inlet current and to respond to fault currents that may exceed this level.

The term is relevant in both residential and industrial settings. For building installations, the ontvangststroom influences the rating of main fuses or breakers, the design of the incoming electrical cabinet, and the energy metering at the point of connection. In industrial contexts, it is important for coordinating with upstream feeders, transformers, and protection schemes, and for documenting compliance with electrical standards and installations.
