The Vanguard CVT-765 is a microprocessor-based, single phase, automatic, transformer turns-ratio tester. This portable test unit is specifically designed to measure the turns-ratios of Capacitor Voltage Transformers (CVT’s).
The CVT-765 determines the transformer turns-ratio using the? measuring method. It uses a 7440 Vac excitation voltage source to accurately measure the turns-ratio of Capacitor Voltage Transformers with a rating of up to 765KV. The transformer turns-ratio is determined by precisely measuring the voltages across the unloaded transformer windings.
- Standalone or computer-controlled
- Can test CVT’s rated up to 765 KV
- Displays turns-ratios from 75-15,000
- Calculates turns-ratio percentage error when nameplate voltages are provided
Vanguard CVT-765是一款基于微处理器的单相自动变压器匝数比测试仪。该便携式测试单元用于测量电容式电压互感器(CVT)的匝数比。
CVT-765使用测量方法确定变压器匝数比。它使用7440 Vac激励电压源精确测量电容式电压互感器的匝数比,额定值高达765KV。通过精确测量无负载变压器绕组两端的电压来确定变压器匝数比。
