current transformer

 Using imported outdoor epoxy resin for casting.

 Using tap of secondary winding to have different current ratio

 We can make high precision current transformer of 0.2S or 0.5S for measuring.

 Pollution class IV

 Ambient temperature -45-+45

 Raed secondary current 5A or 1A.

 Rated frequency 50Hz or 60Hz

 Rated insulation level 12/42/75/kV

The current transformer are in accordane with GB1208 and IEC185 standards.

To protect measuring instruments against short circuit currents. To sense abnormalities in current and give current signals to protective relays to isolate the defective system.

BASIC FUNCTIONS OF CTs ARE To reduce line current to a value which is suitable for standard measuring instruments, relays etc.
