User safety is paramount and the Megger BALTO provides the automated monitoring of the system and temperature
guarding of the ultra-caps.
The Megger BALTO provides :
A Quick test to determine the approximate Circuit Breaker Trip Current - Ids.
An Automatic test with current increase slope according to IEC 61992-2 (Traction Power Substations) and IEC
60077-2 (Rolling Stock) for accurate testing of Ids
Measurement of the DC high speed circuit breaker’s opening time
Testing of the DC protection
Voltage drop measurement according to the DC high speed circuit breakers manufacturer’s procedure
Calibration of the external devices
Automatic recognition of the Current Generator(s)
Auto diagnostic – Control and calibration of current measurement per Current Generator
Flexible current increase management
Graphical display of measurement results
1.3 Applications
The Megger BALTO System was developed for specific applications in the railway field, namely:
Tests of DC high speed circuit breakers for substations 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 trolley buses
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.
