Voltage, current, and temperature measurement for DC power supply
Knick has supplied galvanically isolated transducers for the reliable and precise measurement of the voltage and current in direct current stations for decades. During that time, the company has developed into the world’s market leading in this segment. This is why Knick is the first contact for suppliers to and operators of direct current stations when it comes to mastering special technical challenges: for example, options for monitoring wear to enable predictive maintenance.
Why Knick?
Protective devices in substations must measure current and voltage in order to execute algorithms for short-circuit detection. This requires high-voltage transducers that measure quickly and precisely, and can withstand high loads at the same time. They must keep voltages between 750 and 3000 V DC under control, including temporary surges like those in energy recovery for braking trains, for example. In these high-voltage applications, protection for humans and devices is crucial. Therefore, the strong galvanic isolation of Knick devices is an important factor when choosing a transducer.
