High-Voltage Safe Measurement Systems High-Voltage Safe Measurement Systems

HV Breakout Modules

Direct measurement of current, voltage and power

The HV Breakout Modules (BM) have been specifically designed for safe measurement applications on cables carrying high voltage. Current and voltage are evaluated and the power calculated online in the module.

The voltage is measured directly. Current measurement is performed by a shunt module that includes a differential amplifier, a temperature sensor and a memory chip for calibration data for automatic online temperature compensation.

The HV BM outputs the measured data with a maximum data rate of up to 1 MHz via EtherCAT® interface and simultaneously with a data rate of up to 10 kHz via the additional CAN interface. This allows a high speed data acquisition via Ethernet and at the same time data recording via CAN data logger.

The HV BM is to be inserted into the HV power cables by feeding the cables through PG cable glands into the module and connecting them there. By measuring directly in the module, possible interferences are minimized and the precision of the measurement is increased.

Highlights

Application Fast and Synchronoues Measurements

Fast and Synchronous Measurement with EtherCAT®

The EtherCAT® measurement technology from CSM offers the highest measurement performance: e.g. for multi-channel applications with more than 1,000 strain gauges - / acceleration transducers and applications with measurement data rates of up to 1 MHz per channel. Manufacturers of measurement devices have to cope with continually increasing requirements. Thus, measurement devices have to acquire and process increasingly large amounts of data. The proven CAN measurement technology is hereby often pushed to its limits. This is why the EtherCAT® field bus is setting new standards regarding bandwidth, maximum number of channels and synchronicity of measurement signals.
