TTI current transformers are intended for: - Applying in electric power metering circuits for calculations with consumers; - Applying in commercial electric power metering circuits; - Transmitting metering information signals to measuring, protection and control devices. 28139-12.
Copser tinned bus used in TTI-A transformers gives opportunity of connecting both copper and aluminum conductors.
Each transformer set includes a cover shielding the secondary terminals ensuring exploitation safety.
Inspection occurrence is established by means of a verification mark impression on the TTI casing and in the passport.
Weight and dimensions are by 10-20% smaller than that of comparable transformers of other domestic manufacturers.
