Current Transformer Testers Manufacturer and Supplier
Current transformer testers check the ratio, polarity, burden, excitation and phase error of current and voltage transformers, for both metering and protection classes. Portable analyzers suit field testing; laboratory systems suit comparator testing of many transformers.
The main selection questions are which transformer types must be tested (CT, PT or CVT), which tests are required (ratio, polarity, burden, excitation, DC resistance), and what ratio range the tester must cover. Before ordering, confirm the model, the transformer types, the test functions, the ratio range, and the delivery terms.

What to confirm before ordering
Before payment, confirm the model, the specification from the current datasheet, the quantity, the price, the lead time, and the delivery terms, in writing. Ask in your inquiry to confirm the payment terms, the trade terms, and the reply time you should expect, rather than assuming any of them. No price, minimum order or lead time figure is stated on this site.
Send an inquiry: include the model, the test or measurement requirement, and the quantity you need. Before payment, confirm the model, the specification from the current datasheet, the quantity, and the delivery terms.
