High-Voltage Safe Measurement Systems 
High-Voltage Safe Measurement Systems
The high risk potential during measurements in high-voltage environments requires an enhanced safety awareness. This means: The user’s life and health should be put in the first place.
CSM therefore strongly recommends to check the high-voltage isolation of these measurement modules on a regular basis in order to ensure their operational safety at all times. This applies in particular, if high-voltage measurement modules are exposed to strong external influences.
For this purpose CSM developed the High-Voltage Isolation Testing Station, consisting of
This station provides options for testing the high-voltage isolation of CSM measurement modules directly on the customer's premises. This is cost-saving and improves the availability of the high-voltage measurement modules as it is no longer necessary to send them to the manufacturer for testing. During a high-voltage isolation test, the isolation of a measurement input is tested against all other measurement inputs, as well as against the housing, the power supply and the CAN bus.
The HV IEPE3 FL1000 has been specifically designed for measuring analog voltages with IEPE sensors, e.g. triaxial accelerometers, in high-voltage environments.
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.
Electric mobility is the future of transportation. The development of modern electric and hybrid vehicles poses new challenges for measurement technology. Not only must the measurement technology for eMobility match the traditional attributes of being accurate, mobile, and easy to use, it must also be safe for the users and the system. CSM high-voltage measurement technology ensures the safety of all measurement applications by means of a HV safe measurement chain from the sensor to the data acquisition.
