Calculate Inrush Current in Three Steps

Equations to Calculate Inrush Current

Why do I need to Use Inrush Current Calculators to Select an Inrush Current Limiter? An Inrush Current Limiter (ICL) can protect electrical equipment from overheating at switch-on due to inrush current. And, because inrush current equals the maximum instantaneous surge of incoming current from a power source, it can equate to as much as 2-3 times the steady state current of the attached device. So, Inrush Current Calculators are the … Continue Reading

Toroidal Transformer Inrush Current Issues Got You Down? We’ve Got the Answer

burnt-toroidal-transformercoloradjust

What You Need to Know About Toroidal Transformer Inrush Current Toroidal Transformer Inrush Current can cause some serious damage if not appropriately managed. Inrush current can cause circuit breakers to trip and fuses to blow. Additionally, it can cause a complete failure of the transformer itself. And if that weren’t enough to give you a headache, excessive inrush current can also limit the total number of devices which can be … Continue Reading

4 Most Common Types of Temperature Sensor

rtd-thermistor-768x512

A temperature sensor plays an important role in many applications.  For example, maintaining a specific temperature is essential for equipment used to fabricate medical drugs, heat liquids, or clean other equipment.  For applications like these, the responsiveness and accuracy of the detection circuit can be critical for quality control. More frequently, however, temperature detection is part of preventative reliability.  For example, while an appliance may not actually perform any high … Continue Reading

Transformer Inrush Current: Limiting a 40VA Transformer

transformer

Have you ever turned on a transformer and heard a loud humming sound? What about having a blown fuse or tripped circuit breaker? These signs can all indicate transformer inrush current. Transformer inrush current describes a spike in current that occurs when you initially turn on your transformer. This spike can be up to 10 times higher than normal current. Why does inrush current occur?  It can happen because large transformers demand a huge amount … Continue Reading
