System Description

SFRA 5000 is a standalone sweep frequency response analyzer for the high accuracy transformer analysis and integrates the STS and TD 5000 family test sets. The SFRA 5000 offers both high precision and portability in a single package, providing all the accessories required for fast, easy to use, reliable, and repeatable measurements.

Without the need for a PC to compare transformer fingerprints, the SFRA 5000 decreases test time enabling the engineer to complete testing in a much shorter period of time than previously possible. The SFRA 5000 has the ability to utilize existing plots saved to internal memory or USB memory stick and use them as a reference during a live measurement. If a problem is detected the test can be interrupted without wasting

any time by comparing the plots real-time, point by point.

The software

SFRA 5000 is provided with its own embedded software, giving the possibility to the engineer to zoom into a portion of the sweep in order to inspect any differences in the plot in more detail during or after a sweep. This enables diagnosis of transformer faults early on in a transformer sweep, without the need for a PC. In fact, the SFRA 5000 does not run on a generic operation system, it is based upon embedded software which is more reliable in the field, especially when used as a standalone instrument.

SFRA Comm Software provides excellent fault diagnosis assistance, ranging from a sophisticated database including multiple search options to automatic fault diagnosis algorithms in accordance with DLT – 911/2004, and also provides excellent graphing functionality for the more experienced user. SFRA Comm provides a simple, swift, and user-intuitive diagnosis of transformer sweeps. The user is able to filter out unwanted sweeps from the built-in database and select up to 9 sweeps to be plotted on one graph.

IEC 600-76-18 Compliance

The SFRA 5000 and accompanying accessories and software have been developed alongside the IEC60076-18 international

the standard for sweep frequency analysis of power transformers.

Connecting Cables

The SFRA 5000 measurement system includes color codedinter connecting leads and cable storage reel. This facilitates quick setup times for testing. The SFRA 5000 and cable reel are signed so that they can be used on-site in the rugged flight case, ensuring the test equipment remains clean when operating in the sometimes challenging field environment.
