Case Study Neutral conductor and transformer overload issues

Goal

To better understand the impact of harmonics on the 600 V bus duct and 2500 KVA transformer.

Solution

Use PowerLogic meters combined with StruxureWare Power Monitoring Expert software to calculate the true capacity of the facility’s transformer. This information helps to solve problems with neutral overloads and transformer heating.

Results

• New bus duct purchased with a neutral ampacity of 100%.

• Temporarily shared harmonic loading between two transformers

• Avoided millions of dollars in damaged product and lost sales.
