GYD test transformer operation box
Scope of application
Used for power frequency AC withstand voltage test of electrical equipment in power system
Performance characteristics
(1) The non-zero position of the carbon brush of the voltage regulator is prohibited from being connected;
(2) Withstand voltage test time can be set freely, and there will be a prompt when the time is up;
(3) Output over-current protection, the over-current setting value is set by coding switch;
(4) The high-voltage measurement is equipped with 500:1, 1000:1 measurement transformation ratio switch, which is convenient to match test transformers with different measurement transformation ratios;
(5) The output ammeter adopts electromagnetic type, which is more resistant to transient short circuit impact.
