Ensure testing accuracy with SFRA accessories
Doble SFRA Accessories include two options for measurement cables, as well as a performance verification cell to help you confirm that your M5400 Sweep Frequency Response Analyzer and leads are working properly.
These accessories give you the opportunity to choose what best fits your testing program and ensure testing accuracy.
Rely on Doble’s M5150 Performance Verification Cell for confirmation that your Doble SFRA field instruments and leads are working correctly. This highly-accurate verification device confirms that your equipment is providing you with results you can trust. The Doble M5150 can be used in the field or in the office allowing you to isolate problems between hardware and cables. Test your SFRA instrument and leads together or test the instrument using the included hook up cables.
The SFRA measurement cables comply with FRA measurement requirements according to IEC 60076-18. Two cable kits are available.
SFRA Classic Plus
This is the default cable shipped with the M5400 in the 18 m (60 ft) length, with classic 3.6 m (12 ft) fixed-length ground connection. It provides ring-style reference ground connection for shorted lead testing and IEC 60076-18 FRA Method 1 (shortest braid) grounding technique with optional braid kit.
IEC 1 with Braid Kit
Use the IEC 1 kit if you test only by the IEC 60076-18 Method 1 technique (shortest braid). The braid kit allows you to test on bushings up to 800 kV level.
