Pienjänniteverkossa

Pienjänniteverkko refers to the low-voltage electrical distribution network. It is the final stage in the power delivery system, bringing electricity from substations to end-users such as homes, businesses, and industries. The voltage in a pienjänniteverkko is typically much lower than in the high-voltage transmission lines, making it safe for direct use by appliances and equipment.

In most countries, the standard low voltage for residential and commercial use is around 230 volts (single-phase) or 400 volts (three-phase). This network comprises a system of underground cables or overhead lines that branch out from distribution transformers. These transformers step down the medium voltage from the grid to the lower voltage suitable for consumption.

The pienjänniteverkko is crucial for the everyday functioning of modern society, powering everything from lighting and heating to electronic devices and industrial machinery. Its reliability is paramount, and its maintenance is a key responsibility of electricity distribution companies. Issues within the pienjänniteverkko, such as faults or overloads, can lead to power outages for consumers. Modern pienjänniteverkko systems are increasingly incorporating smart grid technologies to improve efficiency, monitoring, and fault detection.
