TPU2000R

The TPU2000R is an advanced transformer protection package designed for protection of 3-phase power transformers with up to three restraints available covering the majority of power transformer applications. Sensitive high-speed restrained and unrestrained differential elements protect against internal phase and ground faults. Multiple restraint curves match electronic and electromechanical relays easing retrofits. Flexible harmonic restraint modes prevent false trips during transformer inrush and overexcitation. Phase and ground overcurrent elements for each winding plus disturbance and current level detectors, power metering, digital fault recording and load profile completes a full transformer management system.

Features:

• Six overcurrent protective functions for each winding.
• Programmable logic inputs and outputs.
• Phase compensation for most main winding and current transformer secondary arrangement.
• Electrically Isolated Communications Ports provides superior remote communications.
• Simultaneous communications through front and rear ports via dedicated microprocessors.
• Models available for use with optical CT's.
• Complete electronic draw-out.
• Complete load current metering functions
