The BALTO System was developed to generate, and inject into the circuit, very high and precise DC test currents in order to carry out functional tests on high-speed DC circuit breakers. The problems arising during testing of high-speed DC circuit breakers frequently worry the service and maintenance personnel of rail-way organisations, especially when it comes down to checking and adjusting the thresholds. To meet the requirements encountered in the market, the innovative BALTO system was subject to the specifications worked out on the basis of requests from high-speed DC circuit breakers’ manufacturers and various railways/train operators and public transport companies.

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.

The SPI system is the FIRST high current test systems to permit a user to type in a predetermined current and the SPI system will generate and regulate the requested high current without preheating the test sample by pulsing the output current at high currents. 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” permits users to manually control the unit and also perform automated testing. The SPI unit can also be controlled by a PC for fully automatic testing and report generation.
