TESCO’s new CT Ratio/Burden Tester (Catalog No. 1047) is a lightweight, portable and highly accurate in-service test set to assist in finding lost revenue by testing the accuracy of your meter circuits. The Tester can help determine if there are installations errors, loose connections, incorrect ratios, resistance buildup, open CT’s, or manufacturers defects. The CT Ratio/Burden Tester measures and displays the primary and secondary current of the CT under test, and the ratio of the currents. All test data is stored in the internal memory and easily uploaded to a PC.

The TESCO Field Bag (Catalog No. 1048) is the perfect accessory for the CT Ratio/Burden Tester. The Field Bag can safely hold the tester, charger, and any current probes/cables you might have to go with it.
