The Company
STEVO Electric b.v.b.a. is the pioneer in test equipment for DC high speed circuit breakers and protection relays. Its BALTO series of primary injection equipment was introduced in 2003. In the mean time, over 100 units are in service all over the world. Major transit agencies are using the BALTO system in cities like New York, London, Beijing, Hong Kong and Berlin. Other users are national railways with a DC infrastructure, manufacturers of circuit breakers, train builders, accreditation agencies and big maintenance companies.

Primary injection test equipment
STEVO Electric has compact primary injection test units for rolling stock. These models can provide a maximum current of 3.000A or 4.000A.

For testing the DC high speed circuit breakers in the substations, STEVO Electric offers modular systems. The power units can provide a maximum current of either 3.000A or 4.000A. 5 modules can be easily mounted on a single trolley to provide a maximum current of 15.000A or 20.000A. In a master-slave configuration, maximum currents up to 40.000A can be reached.

The BALTO equipment was designed according to the IEC 61992-2 standard which specifies the requirements for DC circuit breakers for use in fixed installations of traction systems. The system has batteries and ultra-capacitors on board and only requires a standard power outlet of 4A during operation.

Secondary injection test equipment
The BALTO CONTROLLER is a test unit for performing secondary injections. The unit simulates the output of the shunt and provides output voltages ranging from 90 mV up to 10V. Any type of waveform can be programmed by the user. This makes it easy to test Imax, di/dt or any other function of the protection relay.

Breaker Control Drive (BCD)
The BCD is a device to open/close DC High Speed Circuit Breaker. It works with all voltage levels between 24VDC and 110VDC. The device is universal in the sense that it can close/open breakers of various breaker manufacturers.
