Re-engineering Safety in Relay Testing In ANSI-based protection systems, commissioning teams must achieve two goals simultaneously:   guarantee zero CT open-circuit risk   and   complete isolation, measurement, and verification within limited panel space . A well-designed   ANSI-type test switch and plug assembly   transforms these complex tasks into a single, repeatable operation. The   ODES   TSBA Series Test Switch   from ODES is purpose-built for this environment. It inco

The Challenge of DC Signal Diversity Direct-current measurement and control are essential to every power and industrial automation system, yet DC signals rarely come in a single form. In substations,   110/220 VDC control power   must be monitored accurately to ensure dependable tripping and closing operations. In industrial environments,   PLCs and DCSs   typically accept only standardized analog inputs such as   4–20 mA   or   0–5 V , while field devices often output unscal
