Insulation is subject to many elements that can cause it to perform at a less-than-acceptable level. Excessive heat or cold, moisture, vibration, dirt, oil, and corrosive vapors can all contribute to deterioration. For this reason, routine insulation testing is necessary.
Insulation resistance testing can be used as:
- A quality control measure at the time a piece of electrical equipment is produced
- An installation requirement to help ensure specifications are met and to verify proper hookup
- A periodic preventive maintenance task
- A troubleshooting tool
Protec offers a large inventory of insulation test equipment. Here are just a few:
