Split Core Current Transformer

Application:

Incorporated into products used for electric power measurement, electric power quality monitoring, Supervisory Control and Data Acquisition (SCADA), protective relays. The CTSB is used where it is desirable for a stand alone mounting in close proximity to the primary current signal to be monitored. The CTSB is designed for substation BUS bar installations and can be installed without disconnecting the primary current loop.

Features:

• Incorporates high performance electromagnetic cores.
• Characterized by high sensitivity, accuracy, linearity.
• Five(5) standard sizes.
  • 20mm (0.79") x 30mm (1.18")
  • 50mm (1.97") x 80mm (3.15")
  • 80mm (3.15") x 80mm (3.15")
  • 80mm (3.15") x 120mm (4.72")
  • 80mm (3.15") x 160mm (6.30")
• Split core design permits safer and easier installation without disconnection of the primary current circuit.

Specifications:

• Rated Input Ranges: From 100A to 5,000A
• Input Frequency: 50/60HZ
• Secondary Output: 0 to 1 A Full Scale or 0 to 5 A Full Scale
• Accuracy Class: 0.5, 1.0, 3.0 (IEC 60044-1)
• Phase Angle: less than 2 degrees at 50% of rated current
• Burden@ rated current: 1VA to 30VA
• Insulation Voltage: 500 Vac
• Surge withstand: 3,000Vac
• Operating temperature: -15ºC to +60ºC
• Construction: PBT Resin UL flame retardant rating 94-VO housing, epoxy encapsulated.
