1.1 DISTINCTIVE CHARACTERISTICS
1.2 GENERAL DESCRIPTION
TheMantaMTS-3000 is a flexible modular testsystem,geared particularly towards protectiverelay
testing,but configurablefornumerous otherapplicationsrequiring ACand/orDC voltageand/orcurrent
sources.
Systemscan beas simpleas a single phaseAC current source,oras complex as afull threephaseAC
voltage and current source with DCvoltageand current, multi-channel digitalinput operation sensingand
digital output control,and accuratetiming measurement capability.Multi-systemcontrol,with onesystem
functioning as themaster to oneormore slave units,is also possible.Aneconomically priced system may
beconfigured withonly theminimumnumber offeatures required for today’s applications, with the
flexibility toexpand astomorrow’s requirements and budgets dictate.
TheMTS-3000 is specifically engineered forashortlearning curve.A ‘VectorControl’modeprovides
forindividual amplitudeand phaseadjustmentof allACvoltageand current outputs,withtheadded
convenience ofnumerickeypad input for quick absolutecontrolsettings, orrotary knob controlof
incremental changes to settings. Additional ‘intelligent control’modes automate much ofthesetup
required for three phase testapplications, and providesingle-inputcontrol ofmultiple parametersas
found,forexample, during phase-to-phase orthree phasefaultsimulations.
A unique featureoftheequipment isits ability to automatically test many protectiverelaysusing built-in
automatedtest routines.This permits fast,consistent testing forroutinework that may not justify the
expenseandlearning curve necessary forfull computerbasedtesting.Fieldreports canbe generated on
the spotusing aportableprinter.
• Uniqueexpandablemodular design.

common relayelements.
• Outputtestreports directly to aprinter.
• On-orOff-line programming via keypad and/or
rotary knob.

0$17$#7(67#6<67(06 CU M004 01A
An MTS-3000 System consists of a Control Module (CM), and one or more AC output modules. These
modules connect together to form a stack, with the control module at the top.
An AC Current Module (ACI), an AC Voltage Module (ACV), or an AC Voltage/Current Module (ACV/
I) may be easily added or removed from a stack to configure the system to your needs. All the required
electrical connections are made when a module is added to the stack. The CM recognizes and configures
the system for all the modules in a stack on power up. This "plug and play" capability allows modules to
be added or removed at any time.
1.3 APPLICATIONS
1.3.1 Standard Applications
• Static and dynamic testing of virtually all protective relays.
• Calibration and verification of V, I, W, Z, and Frequency transducers.
• Testing of fault recorders, fault locators, and automatic voltage regulators.
• Testing and calibration of metering systems.
1.4 TERMINOLOGY
The following terminology is used throughout this user’s guide:
1.4.1 AC Current Module (ACI)
The AC current module or ACI refers to the MTS-3060 module. This module can have from one to three
AC current channels.
1.4.2 AC Voltage Module (ACV)
The AC voltage module or ACV refers to the MTS-3040 module. This module can have from one to three
AC voltage channels.
1.4.3 Control Module (CM)
Control module or CM refers to the upper most module that makes up the MTS stack.
1.4.4 Device Under Test (DUT)
DUT refers to the protective relay or similar device being tested.
1.4.5 Dynamic Fault Mode
This mode refers to the fault mode that’s used when performing operate time tests. See Section 4.3.2 for a
detailed explanation.

1.4.6DynamicRelayTesting
Dynamic relay testing refers to testing of relays using instantaneoussteps and/orramping ofvoltage and
currentinputs. To closely simulate the conditions thedevice sees in service, the voltagesandcurrents are
typically stepped from anominal,prefaultlevel,to apredetermined fault level.
1.4.7MTS
The"modular test system" MTS-3000 and its various optionalmodules.
1.4.8OnPanel Testing
This refers totesting ofrelays and relaysystems whilethey’reinstalled onpanels orequipment racks.
This involvesinjecting voltages orcurrentsdirectlyinto thepanel to test the complete system response,
and to verify thecorrect input/output wiring andphasing ofthepanel.
1.4.9Programming Mode
Programming modeis used to presetACoutput parameters foreither prefault orfault state.TheAC
outputs aredisabled whilethesystem is in programming mode.
1.4.10 StaticRelay Testing
This refers to relaytesting by slowly varyinginputs to accurately locate pickup points and to perform
repeatablemeasurements.
1.4.11 Test Mode
TheAC outputs are enabledwhile in test mode.
1.4.12 V/I Module(VI)
TheV/ImoduleorVIrefers to theMTS-3030 module. This modulecanbeordered with either oneortwo
convertableAC output channels. Each channel canoperatein either voltagemode(0-150 V), orcurrent
mode(0-25 A).
1.4.13 WFGModule
WFG refers to waveformgeneration modulessuch astheMTS-3030, MTS-3040,and MTS-3060.
1.5 SAFETY CONSIDERATIONS
TheMTS-3000 can generate high levels ofcurrent and voltage. Incorrect usage may cause personal injury
and/or damageto theinstrument.The usermust be qualifiedto work safely inthe intended application
environment ofthisinstrument.Non-adherence tothefollowingminimum requirements constitutes
misuseoftheModular TestSystem, MTS, and themanufacturer acceptsno liability for damages arising
from such misuse.

The instrument case must always be effectively grounded. The rear panel grounding stud of the Control
Module, CM, must be connected by a minimum 12-gauge wire to a known secure ground. This ground is
in addition to the power cord ground.
All leads and connectors must be in good condition and rated for the voltage and current carrying
requirements. Current outputs must be securely connected with a minimum 12 gauge leads with C-hook
terminals.
MTS outputs must not be connected to live outputs or to live equipment. All outputs must be turned off
before making any changes to the connections. Never exceed the following maximum ratings:
(a) 300V rms to ground on any input, power or control.
(b) 300VDC differential to the contact (external trigger) inputs.
(c) 5Arms or 5A DC through any contact output.
All rear panel fuses must contain properly rated fuses.
1.6 TECHNICAL CONSIDERATIONS
The optional DC current source, when enabled, will source up to 2.5A of DC current out of the two left
terminals of Input 1 of the DIGITAL I/O module. The low impedance nature of this source could provide
the necessary trip path to inadvertently trip an auxillary relay or circuit breaker. The DC current output
only should be used when the protective relays trip output circuit is properly isolated.
1.7 TECHNICAL SUPPORT
The design of the MTS reflects decades of experience in the electric power industry. However, we
recognize that situations may be encountered that were not considered during its design. We encourage
you to forward any questions, problems or suggestions to us either through the representative from whom
you purchased your system, or directly to us via the phone, fax or e-mail numbers found on the front
cover.
