  • Page 11: Introduction

    ABB Distribution Protection Unit 1500R Introduction The Distribution Protection Unit 1500R (DPU1500R) is an advanced microprocessor-based relay that protects electrical power subtransmission and distribution systems. Available for 5 or 1 ampere secondary current transformers (CTs), the DPU1500R uses circuit breaker 52a (XO) and 52b (XI) auxiliary contacts for logic input signals. The DPU1500R can be applied with voltage transformers (VTs) connected for operation at 69 or 120 volts AC phase-to-ground (Wye(Star)), 120 volts AC phase-to-phase (Delta or Open Delta with B phase grounded) or 208 volts AC phase-to-phase (Delta).

  • Page 12: Getting Started

    Getting Started Precautions Take the following precautions when using the ABB Distribution Protection Unit 1500R: 1. Incorrect wiring may result in damage. Be sure wiring agrees with connection diagram before energizing. 2. Apply only the rated control voltage marked on the unit.

  • Page 13: Dpu1500R Quick Start

    ABB Distribution Protection Unit 1500R DPU1500R - Quick Start The purpose of this document is to provide an engineer or technician with all of the necessary information on how to test trip and reclose in a new DPU1500R relay. It will answer all of the questions most frequently asked by users who are not familiar with the relay.
  • Page 14 ABB Distribution Protection Unit 1500R Another thing that can keep the relay from reclosing, regardless of what the settings are, is the way the unit is tested. When the relay is tripped, the breaker status 52A (XO) and 52B (XI) contacts must change state and the fault current must drop to 5% under the lowest pickup within the Trip Failure Time setting or the relay will go to Lockout and issue a breaker failure alarm.

    When connecting to a modem, simply use a 25-pin to 9-pin RS-232 cable. The application program on this disk has been carefully tested and performs accurately with most IBM-compatible personal computers. If you experience difficulty in using WinECP, use its online helper or contact ABB at (610)395- 7333.

When you enable its MDT mode, a DPU1500R/2000R on a bus breaker can be programmed to provide primary protection for the bus and backup protection to feeder breakers.
  • Page 170 ABB Distribution Protection Unit 1500R/2000R 9/99 Pickup Auxiliary (PA) Relay During a feeder fault condition, the Pickup Auxiliary high-speed relay disables the 50P-1 and 50N-1 functions of the bus DPU1500R/2000R. This prevents the bus DPU1500R/2000R from tripping the bus breaker before the feeder relay has a chance to clear the fault.
  • Page 171 9/99 ABB Distribution Protection Unit 1500R/2000R Programming the Bus DPU1500R/2000R The bus DPU1500R/2000R provides high-speed tripping for bus faults, and local backup protection for feeder faults not cleared by their primary protective relays. The bus fault protection is accomplished with the 50-1 phase and ground instantaneous elements.

Programming the Feeder DPU1500R/2000R The feeder instantaneous overcurrent relay requires a faster trip response than the bus instantaneous overcurrent relay.

The series combination consists of one or several down-line recloser(s) and a backup substation recloser.

Get the data from the DPU1500R/2000R and assign ZSC to one of the programmable inputs.

The 2 Phase- 50P Trip is not sensitive to single-phase-to-ground faults.
  • Page 180 ABB Distribution Protection Unit 1500R/2000R 9/99 Application Note AN-26 Single-Pole Tripping of Distribution Feeders The DPU1500R/2000R internal logic and programmable outputs are flexible enough to provide single-pole tripping in distribution applications where a group of three single-phase reclosers is used. This scheme requires that the loads be single-phase connected line-to-neutral and provides the benefit of eliminating unnecessary interruptions of the non-faulted phases.
