OMICRON CP SB1 Switching Box: Automated Transformer Testing Unit
 
The OMICRON CP SB1 is a smart switching unit designed to automate three-phase transformer testing in conjunction with the CPC 100 system. It minimizes manual wiring and testing errors by enabling automatic measurement of transformer turns ratio, winding resistance, and tap changer operation across all phases and taps.
 
Features & Benefits
 
Fully automated three-phase testing for turns ratio, winding resistance, and tap changer operation.
Multiplexes CPC 100 outputs across multiple transformer phases for seamless operation.
Automatic transformer discharge between measurements enhances operator safety.
Eliminates manual rewiring, significantly reducing test time and human errors.
Compact and lightweight unit (~3.5 kg) for easy handling in substations.
 
Material & Build
 
Constructed with high-quality components, the OMICRON CP SB1 supports a maximum voltage of 300 V AC and a maximum current of 6 A DC, ensuring compatibility with a wide range of transformer test scenarios.
 
Use Cases / Applications
 
Ideal for commissioning and maintenance of three-phase transformers in substations, this switching box streamlines diagnostics, providing efficient, safe, and repeatable measurements to improve overall transformer reliability.
