The HV Breakout Modules (BM) Type 3.3 have been specially designed for safe and precise three-phase measurement in HV power cables. The inner conductor currents and outer conductor voltages are directly acquired and output 100% synchronously and phase-synchronously via XCP-on-Ethernet.
HV Breakout Module 3.3 can be used to perform three-phase power analyses directly in HV lines.
For this purpose, the HV Breakout Module 3.3 is inserted directly into the HV power cables by feeding the cables through PG glands into the interior of the module and connecting them there using ring terminals.
The HV Breakout Module 3.3C is connected to the cables via a PowerLok connector system and is interlock capable. This makes this variant particularly suitable for use in test benches.
The outer conductor voltages are measured directly. Current measurement is carried out via shunt modules which contain, among other things, a temperature sensor and a memory for calibration data for automatic online temperature compensation.
The sampling of voltage and current with immediate digitization in the aluminum housing of the HV Breakout Module provides optimum protection against electromagnetic interference.
The power measurement circuit is installed in the HV Breakout Module 3.3. The 3-phase power analysis is performed online in the Vector eMobilityAnalyzer.

The two versions of the HV Breakout Module 3.3 enable the electrical power analysis of electric vehicle engines motors the use of classic power meters and current transformers. The modules are suitable for use in powertrain test benches as well as for mobile real-time measurement in the high-voltage electrical system of test vehicles.
The three-phase measurement with only one measurement device offers enormous installation, cost and space advantages.
With the HV BM 3.3 and the eMobilityAnalyzer software from the Vector CSM E-Mobility Measurement System, a wide range of analyses can be performed: Inverter and powertrain efficiency measurements, E-motor power analysis, harmonic analysis, PWM analysis, three-phase signal analysis and many more.
