We design your transformers in accordance with the latest revision of IEEE Std C57.12.00™ and all tests are performed in accordance with IEEE Std C57.12.90™. Your remanufactured transformer is thoroughly tested for quality assurance as well as specification and performance confirmation. This ensures the transformer is service ready when delivered back to you. We provide full IEEE Class II tests. ## Quality - Oil Sample - Winding Insulation Resistance - Core Insulation Resistance - Ratio - Polarity & Phase Relation - Doble® Power Factor - LTC no load & at load ## Performance - Temperature Rise - Impedance Voltage - Load Loss - Excitation Current - No-Load Loss - Audible Sound Level ## Dielectric - Lightning Impulse - Applied Voltage - Induced Voltage - Partial Discharge ## Functional - Liquid levels and temp gauges - Winding temp gauges - Pressure relief and relays - Vacuum gauges and bleeder valves - Forced air cooling - Current transformers - Tank flow gauges - LTC gauges, relays, and controls - Resistance Temperature Detector (RTD) - Transformer Protection Relay (TPR) - Switchgear - Battery cabinet - Control cabinet - Conduit routing ## LET'S TALK ABOUT YOUR PROJECT ### CONTACT US ![Untitled (175 x 104 px)](https://jordantransformer.com/hs-fs/hubfs/Untitled%20(175%20x%20104%20px).png?width=175&height=104&name=Untitled%20(175%20x%20104%20px).png) Copyright © 2025 Jordan Transformer, LLC (952) 492-2720[tel:9524922720](tel:9524922720) [sales@jordantransformer.com](mailto:sales@jordantransformer.com) 1000 Syndicate St. Jordan, MN 55352 [View map & directions ►](https://www.google.com/maps/place/Jordan+Transformer+LLC/@44.6809913,-93.6376613,16z/data=!3m1!4b1!4m6!3m5!1s0x87f60c58854b0e83:0xc9c223164e96db09!8m2!3d44.6809875!4d-93.6350864!16s%2Fg%2F1tflm_8c?entry=ttu) [follow us on facebook](https://www.facebook.com/JordanTransformer/) [connect with us on LinkedIn](https://www.linkedin.com/company/jordan-transformer-llc)
