FAQ
Q: What is the AC voltage withstand test?
A: The transformer undergoes an AC withstand voltage test where a sinusoidal power frequency AC voltage, surpassing a specified multiple of the rated voltage, is simultaneously applied to the transformer winding and bushing. The test duration is 1 minute.
Q: What instrument is a voltage withstand test?
A: Voltage withstand testing employs a high-voltage source accompanied by voltage and current meters. This critical assessment is facilitated by a specialized tool known as a “pressure test set” or “hipot tester.” This instrument administers necessary voltages to the device while monitoring the leakage current. Fault detection is facilitated through the activation of a fault indicator.
Q: What is the purpose of the withstand voltage test?
A: The withstand voltage test aims to ensure that electrical insulation is strong enough to protect against dangerous voltage, prevent contact with harmful currents, and keep people safe from electrical risks.
Q: How would you test for AC voltage?
A:
1. Select AC Voltage Setting:
– Turn the dial to the AC voltage symbol (ṽ). For digital multimeters (DMMs) with millivolt capability, choose the m ṽ option.
2. Insert Leads into Jacks:
– Insert the black lead into the COM jack.
– Insert the red lead into the VΩ jack.
3. Connect to Circuit:
– Connect the test leads to the circuit. Begin with the black lead and follow with the red lead.
4. Read Measurement:
– Look at the multimeter display to read the AC voltage measurement.
