The voltage relay SPAU 330 C is intended for over- and undervoltage supervision of the busbar phase-to-phase voltage as well as for supervision of the residual voltage of the distribution network in your substation. When fully equipped, the relay also incorporates a digital disturbance recorder module. The relay can also be used in other applications requiring overvoltage or undervoltage protection/supervision, residual overvoltage supervision, or fault event recording e.g. for the protection of motors, capacitor banks, transformers, etc.
Scope
- Overvoltage, undervoltage and residual voltage protection
Product benefits
- Supervison of the busbar phase-to-phase voltage as well as protecting transformer, generator, motor and capacitor bank assets
Product features
- Supervision and protection relay primarily used for supervision of substation busbar voltages
- General-use voltage relay for applications requiring overvoltage or undervoltage supervision
- Optional disturbance recorder module used for verifying the correct operation of the protection relay and for analyzing network operation quantities
- Serial interface for two-way data communication with substation level equipment via fiber-optic bus
- Continuous self-supervision of relay hardware and software with auto-diagnosis for enhanced system reliability and availability
