Industry Focus: Solar
UPS Servis is a Czech based company that specialises in providing power quality services and solutions to the electrical industry. When UPS Servis partnered with Schneider to provide a measurement and monitoring system for two solar projects near Prague, they chose Raztec sensors.
Customer Problem
UPS Servis needed a current sensor for their measurement boards with longevity, accuracy and very specific technical specifications. Their first two suppliers’ products either failed after an unacceptably short time or needed re-calibrating after only a year of use.
“When we talked to a company all the way from New Zealand, Raztec, and our problems were solved. They even modified their design to better match our needs” says Boris Grinac, UPS Servis Managing Director.
Raztec Sensors Solution
Raztec customised their RAZ3 Hall Effect Current sensor to meet UPS Servis requirements. The Raztec sensors and UPS Servis measurement boards are installed in a harsh environment. Temperatures during summer on sunny days can exceed 80 ̊C. Now after more than two years of operation the Raztec sensors have shown exceptional reliability, very small zero drift and high gain stability.
RAZ3 Product Data
RAZ3 is a CE certified Hall Effect Current Transducer
offering excellent linearity and low hysteresis with 2%
calibration accuracy. It has a very convenient and
compact machine-insertable package which has mains
voltage rating and compliance.
