The FRA 5311 Sweep Frequency Response Analyser detects transformer winding movements and mechanical failures due to mechanical shock, transportation or short circuits as defined in the IEC 60076-18. It can also be used for diagnostics on rotating machines.
The FRA 5311 is the smallest and lightest device in the industry and is extremely easy to use. Just needs to be plugged into a USB port of any computer (for communications and power) and with the windows based software tests can be performed.
Clever grounding connection guarantees measurement repeatability even at high measuring frequencies.
The additional analysis mode allows easy comparison between curves. In addition, measurements from other SFRA manufacturers can be loaded by using the IEC 60076 recommended XML format or by importing them directly (most common SFRA manufacturers' formats available).
