What is Undervoltage – A Guide
Undervoltage can be loosely defined as when a voltage (mostly in 3-phase power systems) is way below the recommended/intended levels. These systems have an Undervoltage relay that prevents the circuit-breaker from closing; hence the motor, for example, won’t start. The relay thus protects the motor from possible damage if/when voltage is lost or reduced drastically. Is Undervoltage Bad for Electronics? While it might seem harmless at first, Undervoltage is quite harmful to electronic components and the motor as well. Although the motor might be able to start, it won’t work as efficiently and effectively as it is designed (due to altered voltage pulses), causing increased wear and tear. In other words, Undervoltage could have a severe impact on your electronics’ lifespan. Why Is It Referred to As a Brownout? Brownout is the term used to describe the dimming of lights when there’s a voltage drop. Voltage may sag due to a disruption in the electrical grid and could also be imposed to reduce the risk of a total blackout. Brownouts may also be affected to reduce the load on the…
