Calibration System for Electronic Instrument Transformers with Analogue and Digital Outputs

摘要：

A:system calibrating electronic instrument transformers with analogue and digital outputs is described.Its design is based on International Electrotechnical Commission (IEC) standards 600447,60044-8 and 61850-9-1. The measurement uncertainty of the system is evaluated to be less than 0.05% for ratio error and less than 2 minfor phase error.

关键词： calibration electronic instrument transformers electronic current transformers (ECTs) electronic voltage transformers (EVTs) ratio error phase error.
