HV Breakout Module 1.2 +S

Single-phase measurement of shield current, inner conductor current, voltage and power

The HV Breakout Module (BM) Type 1.2 +S is specially designed for single-phase measurements on HV voltage power cables. It is suitable to simultaneously measure power, inner conductor current, shield current and voltage of DC and high-speed AC.

Highlights

  • Measurement of shield current (I), inner conductor current (I) and voltage (U) in HV applications
    • Shield currents up to ±250 A (rated ), ±500 A (peak)
    • Internal conductor currents up to ±1,000 A (rated), ±2,000 A (peak)
    • Voltages up to ±1,000 V (measurement range up to ±2,000 V)
    • Calculation of the instantaneous power in the module
  • Simultaneous EtherCAT® and CAN bus communication
  • Output of shield current, internal conductor current, voltage and instantaneous power with up to 1 MHz measurement data rate
  • Online analysis of shield currents and other variables with the Vector eMobilityAnalyzer

Description

The HV BM 1.2 +S is inserted directly into the HV power cables (HV+/HV-) by passing the cables through PG glands into the interior of the module and connecting them there using ring terminals.

The voltage is measured directly. The current measurements are performed via two shunt modules, which contain differential amplifiers as well as temperature sensor and memory for calibration data for automatic online temperature compensation. One shunt is used for the inner conductor current, the other for the shield current.

The HV BM 1.2 +S outputs the measurement data 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.

Applications

With the HV Breakout Module 1.2 +S, shield currents can be measured safely and precisely at many points in the vehicle electrical system. In addition to the measurement of shield currents, the internal conductor current and HV voltage are also acquired - the synchronous measurement of all measured variables in a single module considerably simplifies handling and instrumentation. The high-voltage vehicle electrical system can be designed safely and efficiently on the basis of the subsequent analyses, and serious consequences such as cable fires and premature component failures can be avoided.
