DC Coupon 25cm² exposed with cable tail

DC coupons provide the ability to measure an error-free ‘instant-OFF’ pipe to soil potential, to prove the level of cathodic polarisation achieved on the pipeline. They are particularly useful in areas subject to DC stray currents and on all cathodic protection systems where the synchronised interruption of DC current supplies is complex or impractical. The coupon consists of a steel plate with an exposed area of 25cm² fitted into a 75mm square housing. The connection between the coupon and the cable is potted to stop the ingress of moisture. Three standard cable lengths are available, 5metres, 10metres and 20metres. The standard cable used is 6mm² 6491X Blue on the AC coupons and 10mm² 6491X Blue on the DC coupons, other cable sizes or colours can be supplied.
