Overview

 Automation features reduce total project construction and operation costs through elimination of traditional external control switches, meters, and indicating lamps.

Three-Winding Current Differential Protection Protect two- to three-winding power transformers with programmable single- or dual-slope percentage restraint, supervised by a choice of second- and fourth-harmonic blocking or restraint elements, plus fifth-harmonic and dc blocking elements.

Overexcitation Protection Detect overexcitation conditions to prevent overheating and damage in the protected apparatus with the volts-per-hertz elements. Choose definite-time elements, multiple curves, and custom programmable curves for alarm and tripping applications.
