HV SBM_U evo
Housing safely encloses voltage tap (HV+)
The HV SBM_U evo and HV SBML_U evo allow safe voltage tapping (HV+) in HV power cables. The housings protect the voltage taps from environmental influences and ensure HV safety for users and components. The voltage is measured with the HV SAM1 evo.
Highlights
- Voltage tapping (HV+) in HV applications (up to 1,000 V)
- Connection to corresponding HV SBM_I evo or HV SBML_I evo via HV-safe sensor cable (permanently connected to HV SBM_U evo) for signal transmission to HV SAM1 evo measurement module
- Measurements in copper and aluminum cables
Description
The HV SBM_U evo tap the HV+ potential of an HV power cable. The voltage measurement is performed in combination with an HV SBM_I evo (tap HV- potential) with the HV SAM1 evo.
For measurements on HV aluminum cables, the HV SBML_U evo variant is used.
The HV cables are routed through cable glands into the housing and connected inside via ring terminals. All HV SBM_U evo variants also have an insulated feed-through for the shielding inside the module. The HV SBM_U evo is connected to the HV SBM_I evo with a permanently connected HV-safe and shielded sensor cable with a plug connection.

Applications
The HV SBM_U evo taps the voltage potential HV+ of an HV power cable where there is no space available for the installation of conventional HV Breakout Modules. The encapsulated housing of the HV SBM_U evo or HV SBML_U evo allows for easy and safe application.
The measurement data obtained from the HV BM-Split evo and the eMobilityAnalyzer from the Vector CSM E-Mobility Measurement System can be used to perform a wide range of real-time analyses: efficiency measurement of inverter and drive train, harmonic, PWM, ripple analysis and many more.
