Onboard high-voltage power measurements
CSM Computer-Systeme-Messtechnik GmbH - Stand: 1332
In the area of fast high-voltage measurement technology, CSM has developed a line of high-voltage breakout modules (HV BM). The 1- or 3-phase modules can safely, precisely and synchronously measure high voltages and currents in high-voltage environments with a data rate of up to 1MHz. They also offer online high-speed power calculation.
The high-voltage cables are routed into the housing through PG cable glands or special adapters with high-voltage plugs and connected there. Voltages up to ±1,000V are measured directly, while current measurement up to ±800 A is carried out via shunt modules. These shunt modules contain a differential amplifier as well as a temperature sensor and memory to store calibration data for automatic online temperature compensation.
HV BM can output the measured data with a maximum data rate of 1MHz via EtherCAT interface and simultaneously with a data rate of up to 10kHz via the additional CAN interface. This allows for simultaneous high-speed data acquisition via Ethernet and data recording via a CAN datalogger.
