Testkraftförsörjning

Testkraftförsörjning is the Swedish term for the provision of electrical power specifically intended for testing purposes. It involves the supply of controlled voltage or current to equipment under test in a laboratory or industrial setting. The goal is to ensure that test conditions replicate real‑world operating scenarios while maintaining safety and accuracy.

Key components of a testkraftförsörjning system are the power source, the distribution network, and the interface to the test equipment. Sources can be DC power supplies, AC sources, or specialized high‑frequency signal generators. The distribution network includes isolators, fuses, and voltage regulators to protect equipment from transients and to shape the waveform. Interfaces may use BNC, SMA, or DIN connectors depending on the standardized test rigs.

Standard safety practices require isolation from mains supply, the use of surge protection, and adherence to national regulations such as the Swedish Electrical Safety Agency (Elsäkerhetsverket). Frequently referenced standards include IEC 61557 series for electrical equipment for testing and measurement, and IEC 61000 for electromagnetic compatibility in test setups.

Typical applications are found in automotive, aerospace, and electronics industries where components must be tested under varying electrical loads. Testkraftförsörjning is also crucial for calibration of measurement instruments and for the validation of design specifications before mass production.

By delivering precise, repeatable power conditions, testkraftförsörjning enables engineers to evaluate performance, identify faults, and certify compliance with regulatory and internal quality standards.
