ORION 集合式電表電驛 (SMPR)

ORION  集合式電表電驛 ( SMPR )
 

SMPR 乃設計用於正常狀態下或受到干擾下量測線路和接地RMS及電源RMS電壓。該信號經由本電驛微處理器進行處理，以便採取ANSI、IAC或IEC標準所規定的保護措施。 斷路器或隔離器的操作狀態也會發出訊號。

適用
◐  公用饋線、發電廠及工業配電系統之一次側及備用保護
◐  變壓器、高架線、電纜及發電機等保護

量測項目
◐  (27) Undervoltage
◐  (32) Directional power
◐  (37) Undercurrent
◐  (46) Negative sequence current
◐  (47) Phase-sequence voltage
◐  (50) Instantaneous phase overcurrent
◐  (50N/50G) Instantaneous ground overcurrent
◐  Overload alarm pickup level
◐  (51) Inverse time phase overcurrent (51N/51G) inverse time ground overcurrent
◐  ANSI, IAC or IEC/BS142 curves included: Moderately inverse, Normal inverse, Very inverse, Extremely inverse, Definite time
◐  (55) Power factor
◐  (59) Overvoltage
◐  (68) Blocking output
◐  (81) Underfrequency and Overfrequency
◐  (86) Lockout
◐  Accumulated KA per phase on breaker interruption
