- FTL testblock with dust cover and current disconnect pinThe FTL is a test block for interfacing substation devices (protection relays, fault recorders, revenue meters, ... ) to the voltage and current transformers and to other equipment on the system side of a power grid.
- The FTL test block uses disconnect pins to isolate the substation devices from the system side equipment. Once isolated, secondary injection can be performed using banana jacks on the front side of the test block.
- Finger-safe There are no exposed metallic parts on the FTL test block, greatly increasing safety during testing. Even the back-side is finger-safe.
- Keyed Disconnect Pins Disconnect pins are keyed to the corresponding slots of the test block, preventing mistakes and errors during test.
- Less than 2 mΩ internal resistance Thanks to the patented construction, FTL test blocks have an extremely low internal resistance. This decreases the burden placed on instrumentation transformers and also reduces heat dissipation inside cabinets and panels.
- Over 100 Models and Counting Models with 8, 10, 12, 14, 16, 18 or 20 poles. Any combination of currents, voltages or trip signals. Custom labeling. The right FTL test block either already exists or can easily be created.
- Ideal for Retrofit of Older FT Switches The 10-pole models use the same panel cutout as the older FT switches. Even the terminal labeling is the same. That means that you can have the increased safety and efficiency from the FTL without having to change your engineering drawings.
