Product Description:

The 745 Transformer Protection System™ is a high speed, multi-processor based, threephase, two or three winding, transformer management relay intended for the primary protection and management of small, medium and large power transformers. The 745 combines percent differential, overcurrent, frequency, and overexcitation protection
elements along with monitoring of individual harmonics, and total harmonic distortion (THD) in one economical package.
The relay provides a variety of adaptive relaying features:
• Adaptive harmonic restraint which addresses the problem of false tripping during inrush
• Adaptive time overcurrent elements which will adjust their pickup settings based on the calculated transformer capability when supplying load currents with high harmonic content
• Multiple setpoint groups which allow the user to enter and dynamically select from up to four groups of relay settings to address the protection requirements of different power system configurations
