Metal oxide varistors are thermally protected and designed to withstand not only high-surge energy, but also steady-state overvoltages.
Switchgear offers an option for applications ranging to 34.5 kV and requiring 16-kA symmetrical short-circuit duty. Equipment includes 600-amp load-interrupter switches and fault interrupters, sealed in a SF6-insulated, elbow-connected tank.
Breaker racking system allows operators to perform racking procedures from 40 ft. away, rather than directly in front of a cell and within a breaker's flash boundary. Designed to work with most medium-voltage switchgear breakers.
Siemens Energy & Automation
DC Power supply dissipates little heat, has low electromagnetic emission and operates continuously at full-rated output. The AX500 series is designed specifically for manufacturing, laboratory and education applications.
Power correction system uses active filtering to respond to harmonics with cancellation waveforms. The Accusine system also reduces harmonic-related overheating of cables, transformers and switchgears.
Surge protection system uses a zoned, whole-building approach for power and data quality in three strategic areas and at three voltage ranges.
Wireless monitor keeps plant engineers in constant contact with power
systems via remote technology and the Internet. Devices include programmable alarm conditions and flexible messaging contacts and methods.
Status monitor provides instant verification of control circuits in substations. Continuously monitoring up to eight user-programmed set points, the CCSM alarms locally or via SCADA when an abnormal condition exists.
Rotary UPS gives up to 12 seconds of batteryless ride-through. The STARSINE model is rated from 315 kVA to 2.2 MVA, with nominal voltage from 480 volts AC to 4,160 volts AC.
