CT's and Hall
Sensors
P&B can supply appropriately rated Protection
Class CT's with its relays. The CT's can be supplied in plain ring
or bracket format with terminal lugs as standard. They are UK made
and conform with IEC185:1987.
Electrical Requirements
The electrical requirements of Current Transformers
are defined as:-
Ratio
VA Burden
Accuracy Class
Accuracy limit Factor
For example: 500/5, 2.5 VA Class 10P10
CT's for small motors are often very large
in terms of size and cost. For this reason P&B manufacture a
range of Hall Effect Sensors. The H E Sensors range from 10 to 150
amps and are supplied in a box that measures 233 mm long x 93 mm
wide x 36 mm deep. They are for use with the Microvision and Supervision
ranges of Intelligent Protection & Control relays.
