Description of Turns Ratio Tester Verification Device

The Vanguard ATRT Check Box is designed to verify the field performance of all Electronic Transformer Turns Ratio Testers. It can also be used for trouble-shooting and servicing Electronic Turns Ratio Testers.

The ATRT Check Box uses a toroidal auto-transformer with different taps to give the precise turns-ratio. The design uses a nickel-iron superalloy core to minimize excitation current in order to achieve very accurate turns ratios.

Up to 250 Vac excitation voltage can be applied to the ATRT Check Box, allowing it to be used with virtually all turns ratio testers on the market.

The ATRT Check Box offers the following turns ratios: 1:1, 2:1, 5:1, 10:1, 20:1, 50:1, 100:1, 200:1, 500:1, 1,000:1, 2,000:1, 3,000:1, 6,000:1, and 12,000:1. A turns ratio calibration certificate is provided with each ATRT Check Box.

  • Field performance verification of all electronic turns ratio testers
  • Up to 250 Vac excitation voltage
  • Up to 12,000:1 turns ratio
