CT and PT Analyser is designed to determine the conversion ratio error and phase shift error values of current and voltage transformers according to EN 61869 standard.
It automatically determines the following values:
- CT Transformer Conversion Rate
- PT Transformer Conversion Rate
- CT Phase Angle
- PT Phase Angle
- Load Impedance
- Secondary Winding Resistance
- CT Polarity
- CT and PT Excitation and Saturation Point

GENERAL INFORMATION
What is CT PT?
CT : Current Transformer
PT: Potential Transformer
PT voltage transformers and CT current transformers use the principle of electromagnetic induction to convert high voltages to low voltages or large currents to small currents to provide suitable voltage or current signals to measuring instruments, protection devices and control devices.
