IDMT Over Current Relay Trainer (Model : XPO-PRT/OCR)

The IDMT Over Current Relay Trainer (Model: XPO-PRT/OCR) is an advanced tool designed to facilitate in-depth studies on the characteristics of Inverse Definite Minimum Time (IDMT) and Definite Minimum Time (DMT) overcurrent relays. To enhance experimentation, the trainer comes with a set of 7-8 associated relay testing panels, mounted in a lightweight and sturdy aluminum profile flat demo panel system. Each panel features an ABS molded plastic sturdy enclosure and colorful screwless overlays displaying circuit diagrams and connection tag numbers for effortless understanding and connection. The XPO-PRT/OCR is not only an ideal tool for educational institutions but also proves valuable for postgraduate projects and research purposes.

SALIENT FEATURES

  • Facilitates characteristics of IDMT/DMT over current relay.
  • Each of above trainer has built in requisite relay testing kit typically consisting of voltage injector, current injector, elapsed time counter (1 msec resolution), trip relay logic etc.
  • The trainer need a few set of associated relay testing (current/voltage injection etc.) panels (7-8 nos. typically) which are mounted in a light weight sturdy aluminum profile flat demo panel system. Do not need any separate testing kit.
