LINAM TPR
Underground Test Point Reset Fault Indicator
The LINAM TPR is an underground fault indicator that attaches to capacitive test points in single- or three-phase systems. It replaces the protective cap on capacitive test points, acting as the new cap with the added benefit of providing fault indication. The TPR eliminates the need to account for the position of the concentric neutral, as is common with cable-mounted fault indicators, and automatically resets upon system voltage restoration. The TPR is easy to install with any industry-standard hot stick and the molded rubber hook eye. Powered by voltage, the TPR does not have a minimum load current requirement, making it great for lightly loaded circuit applications. For basic insulating plug (BIP) applications, the TPR offers a model option that works for 600 A applications without a test point on the T-body.

Easy, Cost-Effective Solutions
Choose the most cost-effective fault indicator in the industry for elbow test point applications. The TPR is easy to install on most brands of 200 A- or 600 A-class elbows with capacitive test points and is ideal for pad-mounted transformer and switchgear applications.
BIP Without a Test Point
Select the TPR model option for a BIP voltage reset boot. This model works for 600 A applications without a test point on the elbow or T-body. It receives power and resets from the BIP voltage and senses the fault current with three cable-mounted sensors.
Fault Indicator for Wind Farms
Determine the fault location and restore operations in wind farm collector systems. Wind turbine outputs are fed through a transformer and distributed overhead or underground to a collector substation. The voltage will then be stepped up by the collector substation transformer to the utility transmission voltage. A single fault can disable from one to an entire line of turbines. TPRs help operations personnel quickly determine the location of the fault, isolate the faulted section, and restore the balance of the wind farm.
Solar Photovoltaic Plants
Apply the TPR in solar photovoltaic plants that use terminations equipped with capacitive test points located on the T-body of 600 A terminations.
Single- and Three-Phase Feed-Through Pad-Mounted Transformers
Monitor the cable in feed-through transformers to quickly identify faults, including those caused by dig-ins, aging cables, and wildlife.
Junction Cabinets
Speed up fault indicator deployment in junction cabinets on elbows and T-bodies with test points. The simple installation of the TPR is ideal for the space constraints and large number of cables in the cabinets.
Low Load Current
Install the TPR model option for a BIP where there is insufficient load current to power a current reset fault indicator. The TPRs use voltage for power and reset.
