The HV Breakout Module (BM) type 1.1 has been specially designed for safe and precise single-phase measurement in single HV voltage power cables. Inner conductor current and voltage are measured directly and the instantaneous power is calculated in the module.
The voltage is measured directly. The current is measured via a shunt module which contains differential amplifier as well as temperature sensor and memory for calibration data to perform automatic online temperature compensation.
The HV BM outputs the measurement data including the module-internal temperature values with a maximum data rate of up to 1 MHz via the EtherCAT® interface and simultaneously with a data rate of up to 10 kHz via the additional CAN interface. This enables fast data acquisition via Ethernet with simultaneous data recording via CAN.
The HV BM is inserted into the HV power cables by passing the cables through PG glands into the interior of the module and connecting them there with ring terminals. Alternatively, the cables can simply be installed using customer-specific cable connectors. By measuring directly in the module, rather than over sensor cables, possible interferences are minimized and the precision of the measurement is increased.

Typical applications for these HV Breakout Modules are measurements on single or separated HV+ and HV- cables, for example between HV battery and inverter as well as on accessories such as air conditioning compressors, electrical heaters and DC/DC converters.
For the analysis and validation of the high-voltage vehicle electrical system, the HV Breakout Modules are particularly suitable due to their robust design, uncomplicated installation and precise measurement results.
The measured internal conductor currents and voltages form the basis for further analyses with the Vector CSM E-Mobility Measurement System.
