Encapsulated HV Split Breakout Module

Active Shunt module for precise measurements in a very confined space

The HV Split Breakout Module open (HV SBM_I open) is particularly suitable for current measurements in very confined installation spaces, e.g. on busbars. In addition, the potential HV- is tapped, which allows the voltage measurement to be performed in the HV Split Acquisition Module (HV SAM).

Highlights

  • Current measurement and voltage tapping (HV-) in HV applications in very confined spaces
    • Currents up to ±1,000 A (rated ), ±2,000 A (peak)
  • Data transmission to HV SAM measurement module (HV Split Acquisition Module) via HV-safe sensor cable

Description

The encapsulated shunt modules in the form of the HV SBM_I open contain the measurement shunt, the temperature sensor for automatic temperature compensation and the measuring electronics. With these active shunt modules, the influences of external fields are minimized. Pseudo signals, hysteresis effects, system-related noise, characteristic shift or offset errors are avoided.

The voltage (HV-) is also tapped in the module. The voltage measurement takes place in the HV SAM (HV Split Acquisition Module) in combination with a voltage tap via a suitable sensor cable.

The HV cables are screwed to the M8 bores of the shunt module using ring terminals. The HV SBM_I open can be used directly in busbars. The direct measurement in the busbar reduces the necessary space for the installation.

The HV SBM_I open is connected to the HV SAM measurement module via an HV-safe and shielded sensor cable.

Applications

The HV SBM_I open allow precise current measurements in cables that run in narrow installation spaces and offer little space for the installation of the measurement technology. Furthermore, currents can also be measured directly in the busbars, e.g. of HV batteries. The shunt-based measurement (with temperature compensation) provides precise measurement results for further analysis due to the very low interference.

With the measurement data obtained from the HV BM Split Modules and the eMobilityAnalyzer from the Vector CSM E-Mobility Measurement System a variety of analyses in real time can be performed: Inverter and powertrain efficiency calculations, e-motor power analysis, harmonic analysis, PWM analysis, ripple analysis and many more.
