Overview
Overview: The S3 (T) and N3-WRAD active power/reactive power/current combination transmitters have the same excellent performance as the active, reactive, and current transmitter series. With only one set of signals, they can simultaneously measure the active and reactive power and B (A or C) phase current of a line, thus fully reflecting the load condition of the line. Their output methods are common ground output and can operate continuously for a long time. They are transmitters with high performance price ratio. Active power can be measured in both balanced and unbalanced systems. Reactive power is measured using the cross phase method.

Active power/reactive power/current transmitter
Overview
S3（T）TheN3-WRADType active power/reactive power/The current combination transmitter has the same excellent performance as the active, reactive, and current transmitter series,Only one set of signals is needed to simultaneously measure the active and reactive power of a lineB(AorC)Phase current, thus fully reflecting the load condition of the line,It losesThe output method is common ground output, which can operate continuously for a long time and is a transmitter with high performance price ratio. Active power can be measured in both balanced and unbalanced systemsUnified. Reactive power is measured using the cross phase method: suitable for measuring three-phase three wire symmetrical balance systems with frequencies of 50Hz or 60Hz; Reactive power measurement using phase-shifting method: applicableUsed for measuring single-phase, three-phase three wire balanced or unbalanced systems with a frequency of 50Hz or 60Hz, as well as three-phase four wire systems, its phase-shifting circuit ensures transmissionThe input signal does not generate additional errors due to changes in signal frequency within the range of 40Hz-600Hz.

Note: ① System: marked with T, measured using phase-shifting method; No T annotation, measured using the cross phase method.
② The measurement of current in the combination transmitter is separate, and users can customize it according to their system requirementsConnect any current of phase A, B, or C arbitrarily.
③ The value within the output range () is the calibrated value for forward and reverse power output. toMeasurement of reactive power: When the output is negative, it indicates that the capacitive impedance of the system is high;When the output is positive, it indicates that the inductive impedance of the system is high.
④ The calibration of system power can be found in the previous active power annotation: item ②.
⑤ If the user requires other special calibrations, please specify the parameter values in the contract
