PD-MAT400A

PD-MAT400D is a permanently mounted on-line Partial Discharge (PD) diagnostic system. This test device focuses on detecting and analyzing the generation of PD in equipment such as transformers and reactor using acoustic emission detection. The ability to link up to 15 units using an RS-422 allows the user a greater degree of protection for critical substation equipment. Each unit uses four Acoustic Emission (AE) sensors. This unit provides advanced warning of potential failures.

(NOTE: All PowerPD units include software, which allows accessibility of continuous monitoring from your control room computer, via, remote local LAN)

Features

  • Provides pro-active decision making though continuously monitoring and detecting abnormal conditions in high voltage equipment
  • Reduced maintenance expenses by avoiding costly damage to equipment
  • Provides early warning of possible failure and lost of revenue from an unexpected outage
  • Risk management of previously undetected faults
