Eaton's Cooper Power series Multi-tap substation transformers increase reliability and flexibility in the field for electric submersible pump (ESP) applications. The multi-tap transformer steps-up the low-voltage output from a Variable Speed Drive (VSD) to power pumps. With 25 different voltage settings in both delta and wye connections, multi-tap transformers are available with either mineral oil or FR3 fluid.
