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. 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.

This portable current transformer test set allows to perform many different measurements such as saturation, ratio and polarity tests and CT winding resistance test. Substation maintenance and commissioning test equipment T 2000 is extremely appreciated by electrical engineers for its high accuracy and portability.

The ultimate all-in-one circuit breaker analyzer: safer, faster and more accurate than ever. It allows any timing test, motion and speed analysis, multiple contemporary static and dynamic contact resistance measurements, Both Sides Grounded (BSG) tests, Undervoltage condition test and more. All these functions are integrated in a single lightweight test case without the need of connecting additional external modules.
