Current control is a small scale unit manufacturingdevelops severalvarious types of current current transformers transformers [cts] with brand name vertex. These current transformers are current transformersmanufactured as per is2705, 1992 standard, and generallynormally used applied in control panels, in ratios from 30 a/5 a to 5,000 a/5 a or 1 a; . The vertex current transformers current transformers for electronic control units where secondary currents are from 0.1 a to 0.00 5 a, required need to be compact in size and preferably pcb mountable, 30 a/30 ma, 25 a/5 ma, 50 a/5 ma, 100 a/30 ma, etc.; ..There are also protection class cts for relays and electrical panels with inside dimension as per required by customer requirements; and epoxy resign cast cts for securityprotection and measuringmetering as per customer requirements; . The other kinds of vertex current transformers are 3-phase single unit with round or rectangular hole for cable/busbarbus bar; very high accuracyprecision level cts for metering applications; rectangular current transformers as per requirement; core balance current transformers cbct with dimensions to suit customer requirements, normal rating 25 a/5 ma; rectangular current transformers as per requirement; summation cts to measure current of more than one feeder; and special purpose, non standard ratios can be developed. Data required needed for giving providing proper type of ct to meet customer specifications and requirements: primary current, rated and max surge with duration of overload; secondary load with tolerance or va rating; mounting required, inbox, pcb mountable, open for pipe/wire mounting; centre hole diameter or rectangular size; mounting required, inbox, pcb mountable, open for pipe/wire mounting; termination by wire, screw or pcb; if resin cast if required; special colour, mounting if any; and dimensional restrictions if any. ; and special colour, mounting if any. Some of the applications of the vertex current transformers are: control panel for metering and protection; electronic control systems; control panel for metering and protection; ups/inverter; power factor control panels; capacitor control panels; generator panels; power factor control panels; capacitor control panels; welding machines; system protection panels; single phasing preventor; air conditioning controls;motor protection devices; air conditioning controls; digital panel meters; drives; system protection panels; etc.
