Company: NOJA Power Switchgear
Established: 2002
Description: NOJA Power researches, develops, designs, manufactures and supplies low and medium voltage switchgear products world wide. These products include medium voltage reclosers, motor control centres, PLC, protection panels and Scada control panels. NOJA Power provides high quality, quality assured medium voltage recloser related products and services to an international market. The OSM automatic circuit recloser is clearly the most advanced product of its kind on the market today. Not only due to its size and weight but functionality and rated life. The product is available in voltages up to 27kV. The product has been fully tested to comply with the requirements of ANSI C37.60 and utilizes vacuum interrupters encased in a polycarbonate housing inside a powder coated stainless steel tank to provide a fully insulated and solid di-electric system. This unique and patented fully insulated system allows us to produce the smallest and lightest auto recloser available in the market today. The device measures current on all three (3) phases utilizing Rogowski sensors as well as voltage on all six (6) bushings using a capacitively coupled voltage measurement technique from conductive rubber screens. Because the device has the ability to measure voltage and current, the protection and data logging functionality that is available in the RC control is extensive. The RC control and communications cubicle is a micro processor based control that incorporates the protection data logging and communications function in a single micro processor.

Functionality includes:

  • Directional overcurrent protection
  • Directional earth fault protection
  • Directional sensitive earth fault protection
  • Undervoltage protection
  • Cold load pick up
  • Inrush restraint
  • Voltage reclosing control which allows the customer to program loop automation functionality
  • Separate event logs for close open operations & fault protection operations
  • Instantaneous Voltage, Current and Power metering
  • Load profile data
  • Integral RTU providing DNP3 and Modbus protocols as standard combined with our ability to provide and engineer other protocols on request.
