For engineers designing AC measurements that lead innovations in power quality and precision, there's a need for SPLIT CORE CTs that can be quickly installed on power lines and accurately measure from low to high currents, as well as flexible Rogowski coil CTs.
Consequently, J&D offers accuracy for 0.2S and 0.5S CTs that are applicable to Class 0.2S and 0.5S instruments in accordance with IEC 61869-2 and IEC 62053-22. ANSI C12.1-2014 and ANSI C12.20-2015 are standards applied to Class 0.2 accuracy meters for evaluating the accuracy of energy meters. These standards are applied to Class 0.2 and Class 0.6 accuracy CTs according to IEEE/ANSI C57.13-2008. For accurate power and energy measurement, a very low phase angle error is essential. This is a crucial element in ensuring the performance of current sensors and energy meters. The UL 2808 listing meets the 2017 NEC code requirements for on-site installed CTs. Safety certification: UL/EN/CSA 61010-1 3rd edition; Approval: CE mark, RoHS 3. This signifies the fulfillment of safety requirements related to transformers installed on-site.
When selecting a CT, first identify the style: split-core (open), flexible Rogowski coil, or solid-core (non-open). Evaluate the CT's accuracy, maximum load current, primary conductor size, and its secondary output connection to the meter. For the secondary output connection, choose between the cable connector, terminal method, or the RJ12 method.
