jännitepoikkeama

Jännitepoikkeama, also known as voltage anomaly or voltage deviation, refers to a departure from the nominal or intended voltage level in an electrical system. This deviation can manifest as either a voltage increase (overvoltage) or a decrease (undervoltage) from the standard operating voltage. These anomalies can occur for a variety of reasons, including fluctuations in the load demand, faults within the power grid, issues with voltage regulation equipment, or problems at the power generation source.

The impact of jännitepoikkeama can range from minor inconveniences to significant damage. Undervoltage can cause sensitive electronic equipment to malfunction or shut down, electric motors to overheat and lose torque, and lights to dim. Overvoltage, on the other hand, can stress and damage electrical components, leading to premature failure, insulation breakdown, and potential fire hazards. In industrial settings, consistent voltage deviations can reduce the efficiency and lifespan of machinery.

Maintaining stable voltage is crucial for the reliable and safe operation of electrical networks and connected devices. Power utilities employ various methods to control and regulate voltage, such as tap changers on transformers and capacitor banks. Understanding and monitoring jännitepoikkeama is an essential aspect of power system management to ensure optimal performance and prevent costly damage.
