Measure Resistance of Magnetic Windings with the Raytech WR14

  • Uncategorized

RatechWR14The Raytech WR14 Winding Resistance Meter is a battery or line-operated, field-portable instrument designed specifically to measure the dc resistance of all types of magnetic windings safely and accurately. It can test transformers and rotating machine windings and perform low-current resistance measurements on connections, contacts and control circuits.

Features:

  • Charges inductive loads up to 1500 Henry
  • 2 independent measuring channels
  • Heavy-duty protection circuitry
  • Simple touch screen operation
  • Data exchange with USB-Key
  • 2 Temperature inputs
  • High power DC Supply (15A/30V)
  • DC Current adjustable for resistance values from 0.05 μΩ to 100 kΩ
  • Fast Discharge unit
  • Discharge Indicator – visible and audible indicator for discharge status
  • Demagnetizing Circuit (world unique)
  • Warning device output to show “transformer under test”
  • Emergency stop push button immediately turns off power and starts discharging
  • Internal Printer
  • Data Storage of up to 10,000 measurements
