These type QL transformers have passed the UL K-factor testing program. K-factor is a unit measuring a transformer’s ability to withstand the harmonics content of a system.
- K=4- Welders- Induction heating- HID lighting- Fluorescent lighting
- K=13- Telecommunications equipment- Classroom facilities- Healthcare facilities- Production lines- SCR variable speed drives
- K=20- Office buildings- Data processing equipment- Adjustable speed drives- Computer installations- Instrumentation

Example 9T14A1001G03 changes to 9T14S100G03. To specify a stainless steel enclosure for a copper transformer, substitute an "Z" in the fifth character in the GE catalog number. Example 9T14C1004G03 changes to 9T14Z1004G03.
