Load Bank Testing | Part 3 | Choosing the Right Load Bank

During testing with a resistive only load bank, a system that is sensitive to transient voltage dips would not necessarily provide an indication of a power supply or system condition that would lead to a potential problem during operation.

Load Bank Testing | Part 2 | Key Reason for Load Testing

The key reason for load testing is that many generator sets seldom run under full load conditions after the manufacturer’s factory testing. Though tested in compliance with the regulatory requirements that permit use of actual loads, over time, this practice can lead to conditions that affect performance and reliability. Modern diesel generator sets designed to meet the stringent EPA Tier Level emission standards are designed to be operated at loads higher than 50% for optimum life and performance.

Load Bank Testing | Part 1 | Standards of Certification

In examining the key differences between resistive and resistive/ reactive load testing, and why the latter is necessary, it is important to focus on addressing a facility’s emergency power generation system as a whole by testing the entire system to identify system-wide weaknesses at the time of commissioning and at periodic test intervals to be in compliance with regulatory agencies.
