Bender W1-P23 Current Transformer

The Bender W1-P23 is a window‑type measuring current transformer (CT) from Bender’s W‑series, designed to clamp around a single conductor and feed a safe, low‑level signal to measurement and protection equipment. It carries the manufacturer part numbers B911710 and 911710 and is referenced in Bender documentation alongside devices such as the EDS3065 Portable Insulation Fault Location System, where it measures currents involved in locating insulation faults. As a measuring CT, the W1-P23 provides electrical isolation between the primary conductor and the sensing electronics while delivering a proportional representation of the conductor current to compatible Bender instruments. The W1‑P23 variant is part of a family of window CTs that accommodate different conductor sizes and mounting configurations, enabling quick, tool‑free installation without breaking the circuit. Typical applications include insulation fault location, current sensing for power quality and energy management, and integration with Bender measurement equipment where precise current measurement is required. For exact suitability, verify the W1‑P23’s primary/secondary ratings and mounting details in Bender’s product literature and ensure compatibility with your specific device family.
