CTPT Caliber (Model CTPTC-10.3)
Instrument transformers such as, current transformers and potential transformers are widely used in electrical grids to provide signals to meters and protective relays. Therefore, accuracy testing of current and potential transformers is important for applications in the area of power system protection and metering.
SonaPERT’s CTPT Caliber Model CTPTC–10.3 is a unique, compact, light weight, innovative PC based system developed to meet the highest standards for performing ratio and phase angle error evaluation of both current and voltage transformers in a single test set.
Salient Features:
- Secondary Current range of CT’s from 50 mA to 5A
- USB port connection with PC
- Primary voltage rating of PT’s from 11 kV
- Recognizes accuracy classes of IEC and IS
- User friendly software
