Represents the magnitude of the error vector, obtained by subtracting the measured
synchrophasor of the theoretical value. It is represented as a fraction of the magnitude
of the theoretical value.
In the equation above,
and
are the measured values, while
and
are
the theoretical values of the input signal at the instant of measurement.
All 1A and 5A analog inputs/boards have the proper accuracy necessary for the PMU
solution to be rated as level 1 compliant according to IEEE C37.118 under the condition
below.
Out-of-band interfering signal ³
¹ Any harmonic up to 50
order
² Of input signal magnitude
³
frequency of interfering signal,
nominal frequency and

1.3 Communication Ports, Transmission Rates
The PMU streams have their source port configurable from the port 4712 to 4732.
Always configure different streams at different ports. Only 1 stream can work at once
per port.
The DR60 allows the following transmission rates: 60 frames/second at 60 Hz and 50
frames/second at 50Hz.
1.4 Configuration
To quickly configure the DR60 to transmit PMU, follow the steps below:
