Very compact electronic current and voltage sensors for DC power grids

Petercem electronic current and voltage sensors for dc power grids are entirely based on electronic technology. In contrast to closed- or open-loop Hall-effect technology, no magnetic circuit is used in the sensor. They allow for the measurement of direct, alternating and impulse currents with a galvanic insulation between the primary and secondary circuits. Unlike other currently available solutions such as shunts and CTs, this approach means these sensors are very compact.

These sensors offer considerable energy savings. Only a few watts are required to power the sensor in contrast with traditional sensors. This reduction in wasted energy means there is no rise in temperature around the sensor. It can be fitted both horizontally and vertically: this flexibility means these sensors can be fitted in any position and simplifies the work of integrators.

Advantages of the electric technology

Reliable in extreme conditions
Years of product development and improvements allow us to offer you a product operating from -40 °C to +85°C (-40°F to 185°C). Thanks to their specific designs, which prevent electric and magnetic perturbations, our sensors can be implemented in compact systems or next to high-current or -voltage bus bars.

Continuous operation
For precise energy metering, Petercem sensors guarantee a very low accuracy error – under 0.25% over frequencies up to 100 kHz – allowing your installation to run reliably and efficiently. Get high dynamic performances with representative outputs correctly followed up to 100 A/ μs and 50 V/μs.
