The Complete Solution in one package SFRA in 4 steps Connect Lead set and Zero Check Extend Cable reel, connect Gen and CH1 to clamp 1 and CH2 to clamp 2. Connect clamps together and check for 0dB throughout the sweep range Run sweep direct from front panel or via SFRAComm software Set up the sweep and enter transformer parameters Remotely control and record direct to software in the DUT menu, save sweep to the SFRA45's 1GB or transfer data later internal memory (Data can be saved in XML format and imported to SFRAComm later) 4 SFRAComm software offers a database facility to compare numerous...

Reliable | Repea Decrease Test Time with the SFRA45 Without the need for a PC to compare transformer fingerprints, the SFRA45 decreases test time enabling the engineer to complete testing in a much shorter period of time than previously possible. The SFRA45 has the ability to utilise exisiting 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 picture above illustrates the ability to compare plots during a sweep,...

atable | Accurate Zoom in for greater detail The engineer has the ablity 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. The SFRA45 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.

Ease of use in the Field The SFRA45 measurement system includes colour coded interconnecting leads and "N4L Cable storage reel". This facilitates quick setup times for testing. The SFRA45 and cable reel are designed so that they can be used in situe in the rugged flight case, ensuring the test equipment remains clean when operating in the sometimes challenging field environment. 18m BNC Cable to Transformer Generator, CH1 + CH2 Connections Colour Coded Interconnection Cables Side Compartment to store accessories SFRA45 seated in Flight Case during testing Making the connection An important aspect...

IEC60076-18 Compliance The SFRA45 and accompanying accessories and software have been developed alongside the IEC60076-18 international standard for sweep frequency analysis of power transformers. Transformer Fault Diagnosis SFRAComm 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. As illustrated in the graph below, SFRAComm provides simple, swift and user intuitive...
