Sensors and electronic accessories
Electricity is a “product” that has to fulfil very clear requirements. There must be a cheap and uninterrupted supply at a constant frequency and voltage, without distortion or interference.
While this may sound simple, in practice the steadily growing number of decentralized generators feeding electricity into the grid poses a huge challenge.
Especially in the medium-voltage distribution grid, it is vital to measure the current and voltage in transformer substations with a high degree of accuracy, even in adverse weather conditions. Covering a wide range of applications, from monitoring and remote control to systematic generation and load management, Zelisko’s high-precision sensors are more than up to the task.
The key benefit offered by Zelisko’s voltage, phase current, earth fault, multifunction and combined sensors is a blend of high-precision measurement with straightforward installation and maximum reliability. The sensors function perfectly in virtually any temperature range, and can be easily and quickly retrofitted without major modifications to switchgear or grid infrastructure. They can operate at voltages up to 72kV with rated currents of up to 50kA.
