1.0 Introduction
This user guide contains information regarding the correct use and safe handling of the SPI500. This
user guide is on-board the Smart Touch View Interface, and can be quickly referred to by pressing
the “?” Help button located on the main screen. Please read the section ‘Safety, Warnings and
Standards’. This section contains information regarding your personal safety when using the SPI500.
1.1 Product description
The Model SPI500 is a high current primary injection test system with the flexibility to test a wide
variety of devices such as low-voltage power circuit breakers, molded-case circuit breakers equipped
with thermal magnetic or electronic trip devices, switchgear CT’s, overcurrent relays, and thermal
relays via primary injection. The SPI500 is designed to test a wide range of circuit breakers, with
ratings up to 225 Amps frame size. The unit is fully compliant with NEMA AB-4 test guidelines.
The SPI system is the FIRST high current test system that allows a user to type in a predetermined
current amplitude and the SPI system will generate and regulate the requested high current without
preheating the test sample by pulsing the output current at high amplitudes. The SPI system also has
the unique ability to turn on at the current zero crossing every time for any load by automatically
adjusting the output firing angle. This eliminates DC offset for every circuit breaker type and the need
for the user to determine and manually adjust the firing angle for different loads and circuit breakers.
The SPI system can be operated in a fully automated or manual mode via a full color, high resolution,
TFT LCD touch screen controller (STVI). The optional controller provides the overall system
operations and data storage functions. The unit comes with a USB memory stick which includes the
SPI software to load onto a PC.
The touch-screen controller allows the use of Megger’s PowerDB software, which gives the user the
ability to download a TCC (Time Current Curve) into the SPI test system. By using a downloaded
curve, the user will be provided with Pass/Fail results directly on the SPI test report. This provides
the user with an immediate answer to whether the test sample is working correctly or requires
maintenance.
1.2 Terminology
The acronyms, terms, and definitions used throughout this manual are described below:
1.2.1 Glossary of Terms for Circuit Breaker Testing
The SPI500 software screens prompt the user to select, or set, various values. The values vary
depending on the protective device under test. Many of the terms used are similar in nature and
mean virtually the same thing regardless of the type of breaker. For example, the term Time Dial is
commonly used to define the time dial setting on the device under test. Unfortunately, some of the
terms described here may apply to different types of devices under test in different ways, and thus
may not cover every possible device made. However, it is hoped that this glossary will help the user
to understand every setting value on every device under test.
1.2.2.1 Pickup (Tap / Sensitivity Rating)
A numerical value associated with a tap or sensitivity rating setting on the device under test. It is used
to define a setting value, pick up value, or minimum operating point, of the device under test.
1.2.2.2 Time Delay
It is a numerical value of time, normally associated with the minimum operating time of the device
under test. Low Voltage Power Circuit Breakers are available with three types of tripping
characteristics: Long-Time, Short-Time, and Instantaneous.
