Why get Smart?
„ Megger has had Primary Current Injection with:
– DDA Series
–CB Series
–MS Series
–ODEN Series
So, why Smart Primary Injection….
•
Use new technology to enhance the usability
•
Lower the weight per watt output ratio
•
How about 2,000 Amp in a 44 pound box?

„ Smart Primary Injection – SPI - Key Features
Feature
Benefit
SPI can be controlled by
STVI or PC
Permits users the option to control the system manually from a
“Smart Touch View Interface” or use a PC to automatically
control the unit.
PowerDB is controlling
software
•This simplifies training for both STVI users and PC users since
the system uses the same application
•PowerDB benefits are immediately available, such as test
report generation, database management, trending etc.
Programmable output
current
•Speeds testing by eliminating the manual variac.
•Every other high current system requires user to manually set
output current.
SPI system compares test
results against
manufacture’s time current
curves
•Eliminates the need for the user to manually compare trip
times to a paper TCC curve

„ Smart Primary Injection – SPI - Key Features
Feature
Benefit
Automatically regulates
output current to
programmed value
•Overcomes heating of the trip element which causes the
current to drop during a thermal test
•Maintains a uniform current waveform even with
changing load impedances
Multiple compact portable
systems can be linked
together to generate
higher test current
•Higher test currents can be obtained by adding multiple
units (stacking).
•Synchronization between multiple boxes is obtained by
a single Ethernet cable
PC connects using
Ethernet or USB cables
Wired communication & control is achieved by common
high speed communication cables.
Bluetooth enabled PC’s
eliminate communication
wires
Eliminates the users need for a communication cable.

Smart Touch View Interface Operation
„ Simple intuitive interface specifically designed for:
• Primary injection testing
• Circuit breaker testing
• Ratio CT’s
„ Permits storage of test results in STVI
„ Rugged and simple touch screen interface
„ STVI Uses PowerDB as operating application
„ Test results compared against manufacture’s trip curves
• The STVI will ship with available breaker curves
• Additional breaker curves can be added by downloading
from PowerDB

STVI Operation of SPI
„ Results can be transferred with USB stick or
Ethernet connection
„ STVI connects to SPI using a common Ethernet
patch cable
„ Same STVI can be used on ANY SPI unit
