Cost-Effective Solution—Choose the most cost-effective fault indicator in the industry for elbow test point applications. The Test Point Reset (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. The TPR automatically resets upon restoration of system voltage. The TPR is available for single- or three-phase applications. Choose the auxiliary contact option for SCADA compatibility. An optional junction shield, which is required on all 600 A class applications, prevents false tripping due to adjacent phase effects.
SEL Fault Indicator for Wind Farms—Install the TPR in wind farm applications that use terminations equipped with capacitive test points located on the T-body of 600 A terminations. By selecting a high nominal trip rating and a longer trip response time, you can apply this cost-effective, nondirectional fault indicator to find faults on circuits with distributed generation.
SEL Solution for Solar Photovoltaic Plants—Apply the TPR for solar photovoltaic plant applications that use terminations equipped with capacitive test points located on the T-body of 600 A terminations.
