perkaitimo

Perkaitimo is a Lithuanian noun that denotes overheating or excessive heating of a substance, object, or system. It is formed from the verb kaitinti (to heat) with the prefix per-, which conveys an intensified or excessive sense. In technical writing, perkaitimo is used to describe temperatures that exceed safe or design limits.

In practical terms, perkaitimo commonly occurs in mechanical, electrical, and electronic systems where heat generation surpasses removal. Causes include friction, electrical resistance, poor ventilation, high ambient temperatures, or sustained high-load operation. The condition can affect machinery, motors, transformers, and power electronics, leading to reduced efficiency, accelerated wear, insulation damage, thermal expansion, and potential component failure.

The consequences of perkaitimo depend on the duration and peak temperature reached. Short-term overheating may cause temporary performance throttling or alarms, while prolonged overheating can degrade materials, shorten lifespans, and increase the risk of catastrophic failure. In consumer contexts, overheating is a major safety concern in devices such as batteries, motors, and appliances.

Prevention and management rely on effective thermal design and monitoring. Approaches include adequate cooling and ventilation, heat sinks, thermal insulation, derating for high ambient conditions, and automatic shutdown or throttling when temperatures exceed safe thresholds. Temperature monitoring is commonly performed with thermocouples, resistance temperature detectors, or infrared thermography.
