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
Vanguard ATRT复选框旨在验证所有电子变压器匝数比测试仪的现场性能。它还可用于故障排除和维修电子匝数比测试仪。
ATRT复选框使用具有不同抽头的环形自耦变压器，以提供精确的匝数比。该设计使用镍铁高温合金磁芯来最小化激励电流，以实现非常精确的匝数比。
高达250 Vac的激励电压可以应用于ATRT复选框，使其可以与市场上几乎所有匝数比的测试仪一起使用。
ATRT复选框提供以下匝数比：1：1,2：1,5：1,10：1,20：1,50：1,100：1,200：1,500：1,1000：1， 2,000：1,3,000：1,6,000：1和12,000：1。
- 所有电子匝数比测试仪的现场性能验证
- 高达250 Vac的激励电压
- 高达12,000：1的匝数比
