The Current Transformer Probe and Voltage Clamp Installer has been specially developed for use with CHK Power Quality Loggers and Analysers’ current transformer probes (52 Series) and large black voltage clamps. The installer allows the easy and convenient installation and removal of the current transformer probes and large black voltage clamps on overhead conductors, using a hot stick with a ‘sunrise’ fitting. Suitable CT probe lead extensions and extended voltage leads complete the kit.

The installation can be carried out from ground level or from an approved elevated work platform. Subsequently, users do not have to climb poles using ladders, wear safety harnesses or require another staff to standby (i.e. no need for a ‘buddy’ safety system). This allows for a one-man operation, leading to significant savings of resources.
