3.6 AC Test Step
In this unit, users can set any AC current output and voltage amplitude, phase, frequency and
binary status, etc.
When binary from A to E has change, the output will stop. The t
act
means the action time of binary.
It can be used to test simple protection action value and time.

Figure 3-5 AC manual calibration interface
Calibration interface includes:
Left: users can set calibration parameters.
Right: every phase power factor, active power, reactive power listed according to users
setting.
3.6.1 AC Voltage, Current and Phase Calibration
Users can set any AC output current and voltage amplitude, phase and frequency.
Output calibration power.
3.6.2 AC Action Time Test
Set AC output value;
Connect power output with input of relay; connect the binary output of relay with any
binary input of PM605A.
Output calibration power: After the relay works, the output will be cut automatically.
