MANTA TEST SYSTEMS

I3 Current Mode This current mode outputs a
single current which is switched to any pair of four-
wire current output used for testing 3
Φ
relays.
I3-Wye Current Mode This current mode outputs
a full 3
Φ
wye current. (9.4)
Individual Amplitude Adjustment Mode This
mode allows setting amplitudes of all AC outputs
independently of each other for simulating non-
standard faults (6.7).
Individual Phase Adjustment Modes These are
the phase adjustment modes in which the user has
direct control over the phase of all outputs in all
fault states. (5.12.2, 6.7)
Internal Start Timer Mode In this mode, the
timer starts synchronously with the change from
prefault to fault outputs. (5.3.1)
Line frequency reference mode In this frequency
reference mode, the voltage and current outputs are
phase and frequency locked to the input AC line.
(4.10.1.1)
Local Control Mode Mode used for all front
panel, manual operation. (6.2.1)
Monitor Voltage The voltage presently selected
for voltage, phase and frequency measurement.
(4.9)
Nominal
Φ
-N Voltages These are the A-N, B-N
and C-N voltage settings made while
Φ
-N fault type
was selected. These settings determine the
maximum voltages which can be obtained at any
time. (4.7.1)
Normal Amplitude Adjustment Mode This is
the amplitude adjustment mode in which current/
voltage adjustment automatically adjusts the
amplitude of the faulting voltage(s) or current(s).
All other amplitudes are automatically set by the
MTS-1710 to simulate standard faults (4.7)
Normal Phase Adjustment Mode This is the
phase adjustment mode in which phase adjustment
automatically adjusts phase between the faulting
voltage and current. All other phase relationships
are automatically set by the MTS-1710 to simulate
standard faults (5.12.1)
Operation Mode The operation mode defines how
various inputs affect changes between the MTS-
1710 fault states. The operation mode may be static
or dynamic. (4.2)
Output Levels The present level of the voltage and
current outputs. The output level may be the
prefault, fault or postfault setting, or off. In prefault
state and postfault states, the output level may be set
to off using the [PREFAULT] and [POSTFAULT]
buttons. This overrides the prefault and postfault
settings. (4.4)
Phase Measurement Speed
The
phase
measurement speed of the MTS-1710. This may be
set to normal or to high-speed (1 cycle response).
(5.14).
Postfault State The postfault state simulates the
inputs to the relay after the fault condition and relay
operation. (4.1)
Prefault State The prefault state simulates the
healthy inputs to the relay, prior to the fault
occurrence. (4.1)
PT Location This setting parameter allows
simulation of either line-side or bus-side potential
transformers. For line-side PT simulation,
whenever a simulated breaker is open, the voltage
on the corresponding phase will be zero. For bus-
side PT simulation, whenever a simulated breaker is
open, the voltage on the corresponding phase will
be the nominal (prefault) setting. (5.11.4)
Remote Control Mode Mode used for operation
under computer or external device control. (6.2.1)
