PCS-974 is a dedicated auxiliary relay for transformer nonelectrical protection. This IED provides sixteen high-powerpickup binary inputs for mechanical element monitoring, alarming and tripping. The high-power-pickup design reduces the risk of Electro-Magnetic Interference (EMI) in order to improve reliability. Generally, mechanical relays include winding temperature relays, oil temperature relays and buchholz relays. The relay can be used for transformer and generator protection.The PCS-974 is compatible with IEC 61850 station bus and process bus applications. It supp…More Info
PCS-9671 is a compact numerical relay for two-winding transformers. It can be utilized for reactor or stub-bus current differential protection. It also can be used to protect reactors or implemented as a stub current differential protection in a oneand- a-half breaker arrangement. The restraint current differential protection, unrestraint differential protection and restricted earth fault protection are provided.Comprehensive flexibility is provided via the modular hardware design, scalable function library, programmable logics, configurable I/Os and definable LEDs. This allows us…More Info
