overview
model td6300, a high-precision apparatus to measure the ratio difference and phase displacement for electronic instrument transformers. it has the function of vector measurement to the following parameters: the secondary voltage (maximum 120 v) and current (maximum 6 a) of standard transformers, the secondary ac output voltage (maximum 12 v) and current (maximum 1.2 a) of the detected electronic instrument transformers.
features
● the electronic voltage transformers or electronic current transformers are all supported for detecting.
● measure ac voltage, current and frequency, as well as measure the phase/ratio of v-v, v-i and i-i.
● the accuracy class of ac voltage or current measurement is 0.01 with a frequency of 45 hz to 65 hz.
● at 50 hz / 60 hz, the ratio difference measurement accuracy is up to ±0.02 %, and the phase displacement measurement accuracy is up to ±0.005 °.
● support for displaying multiple units, such as degree, degree-second-second and radian.
● all the input channels can automatically or manually switch the ranges.
● good electrical insulation and protection between all the input channels and measurement loops.
