Series Reactive Power Transmitter,
is a type of device that can isolate input voltage and current signals
and convert them into DC signals output in linear proportion to the input reactive power. It can reflect
the characteristics of the system (capacitive or inductive) and can operate continuously for a long
time. It can be widely use in places where power and non power systems have high requirements
for measuring reactive power. The reactive power is measure using the cross phase method: suitable
for measuring three-phase three-wire symmetrical balance systems with frequencies of HZ or HZ;
The reactive power measure using phase shift method; Suitable for measuring single-phase,
three-phase three wire balanced or unbalanced systems, and three-phase four wire systems with
frequencies of 50 Hz or 60Hz.
