Description
The SPI225 is a high current primary injection test system for all forms of high current testing required in a substation, including testing overcurrent relays, circuit breakers, motor overloads, and current transformers. A single SPI225 is designed to test low voltage molded-case circuit breakers up to a rating of 225 A.
The SPI system allows the user to type in a predetermined current and the SPI system will generate and regulate the requested high current. The SPI system also has the unique ability to turn on at the current zero crossing every time for any load by automatically adjust the output firing angle. This eliminates DC offset for every circuit breaker type and the need for the user to determine and adjust the firing angle for different loads and circuit breakers.
All SPI systems are both fully automated and/or manually controlled. The Smart Touch View Interface (STVI) gives you the ability to manually control the unit and also perform automated testing. The SPI225 can also be controlled by a PC for fully automatic testing and report generation.

Frequently Asked Questions
Will the SPI225 run on a generator?
In most cases the SPI will run on a generator, but if the generator has large frequency fluctuations, it will cause the SPI not to be able to match frequency. Typically an inventor generator works best.
When daisy chaining two SPI225 units, does the input power have to be on the same phase?
Yes. The phase angle into the SPI is the same as the phase angle out of the SPI. Therefore in order to parallel or series outputs, they must be on the same phase.
The unit is labeled 120V or 240V input. Do I need to change any settings or connections depending on what voltage I want to use?
The SPI225 senses input voltage at start up and automatically switches internal taps to get the most power output based on input voltage. Therefore the unit achieves near the same output at 120V or 240V. The only limitation is if the input voltage drops during tests.
Can full output be achieved at the end of a long extension cord?
To get maximum output, a strong source is required. The manual requests a 20 amp services if using 120V. If a long extension cord is used the voltage at the end of the cord will have a large voltage drop at high current. If the input voltage drops, the output will also drop. The unit can work on 120V or 240V. If 240V is used the input current decreases and voltage drop becomes less of an issue.
How long of test leads can be used and still get 2000 amps of output?
When testing breakers the leads should be as short as possible. 2ft leads are recommended. If you need longer leads you can series two units together and get higher output.
