Manual Frequency Test Settings Screen
Figure 96 Manual Frequency Test Screen
Description
The Manual Voltage / Current Test screen is designed to permit manual output control of the
MPRT and provide simple interface for basic relay testing. This control screen allows the user to
apply any value of magnitude, phase angle, or frequency to a protective relay and time the
response.
Operation
This screen can apply set values to visually watch the response of the relay, or the unit can apply
set values and start the timer and await a response time from a protective relay.
This screen can also simulate a three state conditions ( Prefault, Fault and Postfault). A relay
operation time can be monitored by the timer in the Fault stage.
Controls
V1...V4 & I1…I4:
Permits control of any installed voltage (V1, V2,
V3, V4) or current (I1, I2, I3, I4) generator.
Mag:
Controls the Magnitude of any installed voltage
(V1, V2, V3, V4) or current (I1, I2, I3, I4)
generator.
Angle:
Controls the Phase Angle of any installed
voltage (V1, V2, V3, V4) or current (I1, I2, I3, I4)
generator.
