About the product

The SPI500 is a powerful and versatile testing system designed to meet the demanding needs of substation testing. It can handle a wide range of high-current tests, including those for electronic reclosers, circuit breakers, high-speed fuses, and ground fault relays.

With the ability to control up to two SPI500B boosters, the SPI500 can increase its testing capacity by up to three times. Its unique control system ensures accurate and reliable testing, even under changing load conditions.

The SPI500 offers both manual and automatic control options, with the Smart Touch View Interface (STVI) providing easy-to-use manual control and the PC-based control system enabling fully automated testing and report generation.

The SPI500 can test self-powered reclosers like the S&C Tripsaver with the push of one button. Also, the most portable test set for testing breakers under 600 A or for testing Modified Differential Ground Fault schemes (MDGF).

FAQ / Frequently Asked Questions

Which types of self-powered reclosers can be tested with the SPI500?

S&C Tripsaver II, Siemens Fusesaver, Hubbell VersaTech II, NOJA Econlink, ABB Eagle, or most self-powered reclosers on the market.

Is a booster required for testing a 400 A circuit breaker?

Yes. The main unit will test up to a 225 A breaker in most cases, adding a booster will allow up to 400 A breakers to be tested, and a second booster will allow most 600 A breakers to be tested.

Will the SPI500 work on 120V with using a booster?

It is recommended that 208 or 240 be used when using boosters because the input voltage will sag to the unit with high current draw. Best results are to use higher voltage which will have less input current and less voltage sag, achieving higher output.

What accessories are recommended if the SPI500 is used for testing self-powered reclosers?

We recommend the user purchasing a longer cable for the 125 A tap if testing reclosers. This is part number 1016-196.

Troubleshooting

If the user is not able to achieve rated output

There are two main items that can affect the output ability of the unit:

Resistance connected to the output. The transformer in the unit is design to achieve max output with a typical resistance on the output. If connections to the test object are not making good contact or the resistance of the test leads is too great the output ability will be reduced. Consider making better connection or reducing connection length. The user may also consider using a booster in series with the main unit to achieve greater output voltage.
Low voltage on the input. The output voltage the unit can deliver is proportional to the input voltage. If the input voltage is sagging when running a test it will cause reduced output ability. For example, if on a long extension is used, this will create additional voltage drop during high demand tests. To solve this use heavier extension cords (or eliminate as much as possible). Also, if you can use higher voltage such as 240, then the input current will be less which will cause less voltage drop.

When testing a self-powered recloser the user can achieve stable output current.

Self-powered reclosers impedance can dramatically change during primary injection. Therefore, the output voltage of the test set must also dramatically change to achieve a constant current. If the tap selected does not have enough output voltage capability the unit will not be able to achieve requested current during power cycles of the recloser. In most case the 125A tap is recommended for this testing and if the 500A tap is being used, the voltage limit is most likely causing this issue.

FAQ / Frequently Asked Questions

How long of test leads can I use and still push 2000 A?

To push 2000 A out of the main unit without a booster the cables need to be less than 4 feet total. If longer leads are required, then it is recommended to use a booster in series with the main unit and then 10ft or longer leads can be used.

What size generator is needed to run the SPI500?

It is recommended to use a 5000-Watt generator or larger, but the unit will work on a 2000-Watt generator, but output may be limited. During high current tests over 3500 watts of power may be required, and the generator output will typically sag on smaller generators.

Short time pickup is not tripping during testing?

The SPI500 sends output pulses that are 130% of the maximum trip time on the curve. When testing with a generic breaker form, make sure the maximum trip time is correctly filled out. If necessary, the advanced setting will enable you to configure a longer pulse duration.
