Manual Voltage/Current Test Screen
Figure 95 Manual Voltage or Current 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
The Manual Voltage / Current screens can be used to time protective relays in two different
modes.
1. 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 wait a response time from a protective relay.
2. This screen can also simulate four state conditions ( Pre-Fault; Fault; BKR Trip; and
Reclose) and progress through each state condition. A relay operation time can be
monitored by the timer in the Fault or Fault and Reclose conditions.
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.
