Control module SPTO 6D3
Control functions
- status indication for 7 objects, e.g. circuit breakers, disconnectors, earth switches
- circuit breaker/disconnector configuration freely selectable by the user
- remote or local control (open and close) for 6 objects
- setting range for output pulse lenght 0.1...100.0 s
- freely programmable feeder oriented interlocking
Measurement functions
- one pulse counter input for energy pulse counting, maximum pulse frequency 25 Hz
- other measurements require the use of an optional measuring module
- local and remote indication of measured data as scaled values
Measurement functions, with optional measuring module SPTM 8A1 (option 1)
- measurement of three phase currents and three phase-to-phase voltages
- measurement range for current 0...1,5 x I
- accuracy of current and voltage measurement ≥ ±1 % of rated value
- mA inputs for measurement of active and reactive power via external measuring transducers
- accuracy of power measurement ≥ ±1% of maximum value of measurement range
- the energy value can be integrated on the basis of the measured power, alternative to energy pulse
counter
Measurement functions, with optional measuring module SPTM 6A2 (option 2)
- measurement of three phase currents and three phase-to-phase voltages
- measurement ranges, current 0...1,5 x I
- accuracy of current and voltage measurement ≥ ±1 % of rated value
- measurement of active and reactive power using internal current and voltage signals,
the measurement is based on the Aron connection
- power measurement range 0...1,1 x P
- accuracy of positive power measurement ≥ ±2% of rated value
- accuracy of negative power measurement ≥ ±3% of rated value
- the energy value can be integrated using the measured power, alternative to energy pulse counter
Measurement functions, with optional measuring module SPTM 6A3 (option 3)
- measurement of three phase currents and three phase-to-phase voltages
- measurement ranges, current 0...1,5 x I

- measurement of active and reactive power using one internal voltage signal and two current signals,
the currents and voltage used are selected with switches
- power measurement range 0...1,1 x P
- the energy value can be integrated by using the measured power, alternative to energy pulse counter
Auto-reclosing
- 5 auto-reclose shots
- starting time for auto-reclosing initiated by
starting signals AR2 and AR3
- dead time, selectable
- reclaim time, selectable
