Pienjännitejakelu

Pienjännitejakelu refers to the electrical distribution network that delivers electricity at low voltage to end-users. This is the final stage of the power delivery system, taking electricity from substations and distributing it to homes, businesses, and other consumers. In most regions, low voltage is defined as voltages up to 1000 volts AC or 1500 volts DC.

The primary function of pienjännitejakelu is to ensure a safe and reliable supply of electricity at a voltage suitable for direct use by appliances and equipment. This network typically consists of overhead power lines, underground cables, transformers, and various protective devices such as fuses and circuit breakers. Transformers play a crucial role, stepping down the medium voltage from the transmission or primary distribution system to the lower voltage required by consumers.

The design and maintenance of pienjännitejakelu systems are critical for preventing power outages and ensuring the safety of both the public and maintenance personnel. Factors such as the length of circuits, the type of insulation used, and the grounding of the system are carefully considered to minimize energy losses and mitigate risks like electric shock and fire hazards. Modern pienjännitejakelu systems are increasingly incorporating smart grid technologies to improve efficiency, monitor performance, and enable faster response to faults.
