HGQ-II Instrument Transformer Calibrator Calibration Device

HGQ-II Instrument transformer calibrator calibration device is a new instrument improved on the basis of HGQ type. It is an electromagnetic standard instrument that outputs the standard ratio of current to voltage. It is a standard ratio power supply composed of standard components such as instrument transformers standard resistors standard capacitors and corresponding power supplies. It can output standard ratios of current-to-current ΔI/I voltage-to-voltage ΔU/U voltage-to-current ΔU/I and current-to-voltage ΔI/U it is specially used to verify various 1-3 class of transformer calibrators (HEG type and digital display calibrator etc.). It can also be used to verify the secondary pressure drop tester.

Product Features
(1) Use this calibration standard to verify the instrument transformer calibrator. According to the standard and the standard that is basically the same as the one being calibrated you can carry out verification after the wire is connected once.
(2) The readings of the calibration standard and the subject to be tested should be the same and the difference is the error.;
(3) The calibration of the calibration comparator only needs to be balanced once while the calibration of the digital display calibrator can read directly without balance;
(4) The instrument has the advantages of good stability intuitive reading short calibration time and convenient use.
