The BALTO Modular DC high current circuit breaker tester 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. These very high currents are injected in the main circuit of DC high speed circuit breakers and allow control of the entire circuit including the measurement elements, current converters, and protection relays.
Designed with the user in mind, this innovative Megger BALTO system is useable for up to 4000 A, which meets the challenges of the manufacturers and users of DC high speed circuit breakers. To further meet the requirements encountered in the market, the BALTO Modular 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. As such, This instrument has been developed specifically for testing DC high speed circuit breakers at rolling stock, tramways, and primary infrastructure.

APPLICATIONS
The Megger Balto System was developed for specific applications in the railway field, namely:
- Tests of DC high speed circuit-breakers for sub-stations and their protections
- Tests of DC high speed circuit-breakers in locomotives, train sets, subways, undergrounds and tramways
- Tests of electromagnetic contactors (control and main) in tramways and trolleybuses
The Megger Balto system can also be used for other applications where very high currents are required e.g. mining, steel factories, marine and solar.
