What is Contact Resistance Test Why is Contact Resistance

Ductor testing is usually performed using a micro/milli-ohmmeter or low ohmmeter. Measurement of the contact resistance helps in identification of fretting corrosion of contacts, and allows contact corrosion to be diagnosed and prevented. Increase in contact resistance can cause a high-voltage drop in the system, and that needs to be controlled.Get price
