FAQ
Q: What is a Portable Transformer Capacity and Characteristic Tester?
A: It is a portable electrical testing instrument designed to measure transformer capacity and selected electrical characteristics. Depending on the model, these may include no-load current, no-load loss, load loss, impedance voltage, voltage, current and power.
Q: What transformer capacity can the tester measure?
A: The applicable transformer capacity range depends on the specific model. Buyers should provide the transformer rated capacity and voltage levels so the appropriate measurement range can be confirmed.
Q: Can it measure transformer no-load loss?
A: Yes, no-load loss measurement is a common function of this type of transformer tester. The available range and accuracy depend on the model configuration.
Q: Can it measure load loss?
A: Models equipped for transformer load loss testing can measure the relevant electrical parameters used to determine load loss. The required test current and measurement range should be confirmed before purchase.
Q: Can the tester be used in substations?
A: Yes. A portable transformer tester can be used for supported measurements during substation maintenance, commissioning and field inspection, provided that the test conditions remain within the instrument's specified limits and the applicable safety procedures are followed.
Q: What is the advantage of an integrated transformer tester?
A: An integrated tester combines multiple supported measurement functions in one instrument. This can reduce instrument switching, simplify the test setup and reduce manual transfer of measurement data.
Q: Is this tester suitable for transformer manufacturers?
A: Yes. It can be used for production inspection, final testing, capacity verification and transformer characteristic measurements.
Q: What information is needed to select the correct model?
A: The most useful information includes transformer type, rated capacity, primary and secondary voltage, phase configuration, required test items, expected test current, required accuracy and whether the instrument will be used in a factory, laboratory or field environment.
