Together, the new SCT4xxx differential current transformers and the new EL3446-0011 power measurement terminal enable continuous monitoring and condition-based maintenance, saving operators the increased costs of fixed, predetermined maintenance intervals.
The EL3446-0011 power measurement terminal enables comprehensive grid analysis and supports energy management by measuring all relevant electrical data of the supply grid and performing simple pre-evaluation. With 100 mA inputs, it is also particularly suitable for differential current transformers such as the SCT4xxx, which detect even low differential currents as well as leakage currents (type A). The SCT4xxx ring-type CTs for 25 A AC and type A differential current are available in four sizes for 20 to 120 mm round conductors. Combining the two offers particular advantages: The integrated harmonic analysis of the power measurement terminal allows any differential currents to be examined in detail for possible origins immediately and without additional measuring equipment.
