2.
Estimate time for fluid arrival.
Calculate how much time has passed since the injection began.
Use
NRI 302, “The Cable Table”
to calculate the target fluid amount the cable will take in millimeters
of tank height.
Divide the calculated target by the millimeters of fluid currently injected into the cable.
Multiply this number by the amount of time the injection has currently taken. This is the estimated
amount of time left for injection.
Fluid Arrival
1.
Flush the cable.
Flush any contaminants out of the
cable.
Continue to flush until at least
25cc of clear, clean fluid comes
out of the cable.
Figure 14:
Flush the cable.
2.
Reduce pressure to the tailored injection pressure (TIP).
Reduce the adjusted feed pressure (AFP) to the insulation type’s tailored injection pressure (TIP).
The XLPE insulation TIP can be found in
NRI 302, “The Cable Table.”
If the EPR insulation TIP is needed, calculate by dividing the XLPE TIP by 4.
3.
Pin the outlet.
Close the ball valve to the injection tool to prevent fluid spray.
Use the injection tool to insert the plug pin into the IA; then remove the injection tool from the IA.
Check the plug pin hole for leaks and tap the pin in if it is not flush.
Wrap the saddle chain around a rag to protect and keep debris out of the injection tool.
