The power frequency withstand voltage standard between the secondary windings of the transformer
The maximum test current is 10kV/5A when reverse wiring, power frequency or frequency conversion 40-70Hz.
and exists power frequency leakage.
credible measurement results under the conditions of the test current frequency and the system power frequency.
In case of GST, maximum test current is 10kV/1A, and power frequency or variable frequency is 40-70Hz.
the test frequency is close to the power frequency, and stable and credible measurement results can be obtained.
the difference between frequency and power frequency is merely 5Hz.
Insulation leather shoes and electric insulation cloth shoes withstanding voltage less than 15KV are suitable for working environments with power frequency voltage less than 1KV;
Dr Brahms and I changed the power frequency from 21 centimeters to 0.02 centimeters.
The test device is composed of four parts, a power frequency voltage generator,
When the vacuum chamber of the vacuum interrupter drops to 10-2 to 10-1 Pa, the power frequency withstand voltage can still pass.
HZAQ-YS electric insulated liveline rope tester product description Electric insulated rope test bracket dedicated to the insulation rope test power frequency withstand voltage test,
Electric insulated rope test bracket dedicated to the insulation rope test power frequency withstand voltage test,
Power frequency series resonance, because the frequency f can not be adjusted, the sample capacitance value C is a fixed value, therefore, can only be tuned by adjusting the reactor, so the Q value of the power frequency resonance is generally relatively low.
HZAQ-YS electric insulated liveline rope tester product description Electric insulated rope test bracket dedicated to the insulation rope test power frequency withstand voltage test,
Under the power frequency condition, due to the large capacitance of the tested product
the operator should operate at a safe distance(less than 20kV per meter in air), the power frequency withstand test bench must be reliably grounded, and the grounding resistance is less than 0.1Ω.
the ordinary high-power power frequency test transformer are omitted,
it is transformed into a power frequency withstand voltage test system with a pressure regulator and test.
In the power frequency conditions, due to the larger capacity of the test object,
