at the same time, the capacity
relationship is S(sum)=s3×3.
3.4 HZJZ will form the direct current series excitation test transformer, but we need to
add 2 2 u silicon stack into the test transformer which is the highest frequency voltage
after exchange series excitation.
1. Test transformer should be applied into use with control unit, as for how to use
control unit, please see Operation Manual of Control unit.
2. Screening wire should be applied into the direct current test to avoid straying
leakage. After test, discharge rod is applied to release the restored electricity.
3. The end of high frequency voltage filtering capacitance should be connected with
the ground wire, together with crust of control unit to connect with the earth wire.
4. The whole test should follow the regulation in high frequency voltage test site,
should pay more attention to the safety of equipment and body.
