Vuotokytkennöistä

Vuotokytkennöistä is a Finnish term that translates to "leakage couplings" or "leakage connections" in English. It refers to a type of electrical connection designed to deliberately allow a small, controlled amount of electrical current to leak through. This is often a safety feature rather than a fault.

These connections are not typically found in standard household wiring. Instead, they are used in specialized applications where a low-level, continuous current is required for monitoring or control purposes, even when the main circuit is considered "off" or inactive. For example, in some alarm systems or safety interlocks, a small current might flow through a vuotokytkentä to indicate that a circuit is intact and a protective barrier is in place. If the current stops flowing, it signals a potential problem or an unauthorized access.

The design of a vuotokytkentä usually involves specific resistor values or other components that limit the leakage current to a safe and precisely defined level. The purpose is to create a detectable signal without causing significant energy waste or posing a safety hazard. The term emphasizes the functional aspect of controlled leakage rather than an unintended fault.
