 Application


The Iris Power PDA-IV instrument can reliably identify loose, contaminated, overheated or poorly impregnated stator windings to aid in assessing the risk of stator winding failure. This portable instrument is easily connected to permanently installed Iris Power 80 pF Epoxy Mica Capacitors (PDA EMCs) to run tests.
