Testboy GmbH
Using the new Testavit Schuki 1 LCD and 3 LCD, specialists easily check to see if sockets, cable drums or connecting cables are correctly connected in 230 V installations. Due to three LEDs, the connection status can be quickly and clearly determined. In addition, through the finger contact, it can be tested to see whether an impermissible, high contact voltage is applied at the protective earth connection. In addition, using the Testavit Schuki 1 LCD, a 30 mA FI circuit breaker (RCD) can be triggered via a pushbutton.

R.R.Transformers & Equipments
Protective devices such as relays, overload Coils, Circuit breakers and CTS etc. must be checked regularly to ensure that they are always ready to operate correctly, Routine current injection testing will quickly detect faulty or incorrectly adjusted protection circuits / devices & will be possible to prevent serious damage to the system. Primary injection kit is designed to operate on single phase 230/240 volts AC 50 HZ to develop smooth & continuous test current as for loading, calibrating, and testing of CTS, Bimetal Relays, Protection Relays etc. The test set gives high current output at low cost and with inherent safety. The primary current injection testing checks all parts of the protection system by injecting current down the cable / bus bars. The application of the primary current injection sets is to ascertain the current carrying capacity of any Conductor, insulator, connector or calibration of CTS / Bi-metallic relays etc.
