Interface Test System (ITS)
-
The SecuControl ITS is a modular test block designed to meet the stringent safety, reliability, and performance needs of IEC-based substations. With fully finger-safe construction, keyed STP test plugs, and built-in CT Shorting, the ITS enables safe, repeatable secondary injection testing, without the risk of open CT circuits or accidental trips. It is the ideal solution for structured, standardized testing across protection systems.

Long Test Block (LTB)
-
The SecuControl LTB is a robust, finger-safe test block engineered for IEC substations. Paired with keyed STP test plugs and built-in CT shorting, the LTB provides make-before-break operation and patented sequential opening (trip → current → voltage) so relays can be isolated and tested without risk of open CTs or nuisance trips. Its extended rear access (long rear end) brings relay connections closer to the block for neater, more efficient cabling and flush panel integration.

FTL Test Block
-
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.

IPS Test Block & Plugs
-
The SecuControl IPS is the VDE-standard test block system for safe and structured IED testing in substations. Available in flush- or surface-mount versions, it provides a secure interface between relays and the system side, enabling reliable secondary injection without risk of open CT circuits or spurious trips. With finger-safe construction, keyed plugs, built-in CT shorting, and ultra-low resistance, the IPS combines safety, performance, and ease of use in a compact, standardized solution.
