The ZXCT-H Current Transformer Field Calibrator is a high-precision testing instrument developed for on-site verification of current and voltage transformers in power plants, substations, and large-scale user installations. Engineered to comply with SD109 and DL/T448-2000 standards, it eliminates the need for traditional verification equipment while ensuring measurement accuracy and operational efficiency.
