TRANSFORMER ANALYZER

UTEC 505

The UTEC 505 Transformer Analyzer is purpose‑built for testing current transformers (CTs) and potential transformers (PTs) without interrupting service. It enables utilities and service providers to validate CT/PT performance in situ by measuring CT admittance, CT ratio, primary‑to‑secondary phase angle, and service voltage/current/phase relationships.

Product Highlights

The UTEC 505 delivers a powerful combination of functionality, portability, and ease of use. Its ability to operate in-service makes it especially valuable for live testing environments. The instrument features a user-friendly interface, clear on-screen results, and optional add-ons for expanded burden testing.

The UTEC 505 also includes the ability to store and download test results for later analysis. Whether used in a substation, control center, or training lab, the UTEC 505 helps ensure transformer accuracy and system reliability with minimal disruption.

Features

Complete Testing of CTs and PTs
  • CT Admittance Testing – Diagnose CT issues in-service with or without load present.
  • CT Ratio Testing – Determine actual and best-fit ratios while displaying the phase angle between primary and secondary.
  • CT/PT Burden Testing – Introduce a known burden in series with the existing load to evaluate CT performance.
  • CT Core Demagnetization – Restore CT performance in the field by removing residual magnetism.
  • Internal Storage & Data Download – Save test results on-board and export them for recordkeeping or reporting.
  • Line-Powered or Battery Operation – Flexible power options for field use.
