Chapter 2 - Safety Information
Caution:
Check integrity of the PCT connection.
Caution:
Check voltage and current rating of external wiring, ensuring it is
appropriate for the application.
3.7 PERIPHERAL CIRCUITRY
Warning:
Do not open the secondary circuit of a live CT since the high voltage
produced may be lethal to personnel and could damage insulation. Short
the secondary of the line CT before opening any connections to it.
Note:
For most General Electric equipment with ring-terminal connections, the threaded terminal block for current transformer
termination is automatically shorted if the module is removed. Therefore external shorting of the CTs may not be
required. Check the equipment documentation and wiring diagrams first to see if this applies.
Caution:
Where external components such as resistors or voltage dependent
resistors (VDRs) are used, these may present a risk of electric shock or
burns if touched.
Warning:
Take extreme care when using external test blocks and test plugs such as
the MMLG, MMLB and P990, as hazardous voltages may be exposed.
Ensure that CT shorting links are in place before removing test plugs, to
avoid potentially lethal voltages.
