7 Communications

7.1 Prior to the installation of remote control switchgear it is advisable to carry out a

Paknet communications survey using a Paknet test set (CS1051 or CS106-6) to

determine if a suitable signal strength is available. If this cannot be achieved UK

Power Networks Operational Telecoms (or your UKPN nominated contact) should

be consulted so that an alternative can be established.

7.2 A Paknet aerial can usually be mounted onto the switchgear using the bracket

supplied with the equipment - refer to examples in Figure 7-1 and Figure 7-2. For

equipment that is installed in a GRP it is important to orientate the mounting bracket

on the equipment to ensure the aerial is reasonably upright and not bent over by

the GRP roof. It is often necessary to mount the aerial outside of the GRP to get the

best reception - refer to Figure 7-3.
