PT-1 Mendeleevets - Current interrupter
Certification:
Application area
Current interrupter PT-1 Mendeleevets is designed for short-term outages of means of underground communications cathodic protection during the measurement of the polarization potential. The interrupter is used together with a universal diagnostic meter Diacor or other devices that support measurement in current interrupt mode.
Technical details
- Current interrupter PT-1 Mendelevets includes two modules:
- control module (for control of interrupter work and synchronizing from GPS/GLONASS);
- power module (for switching power circuits).
Both modules are in separate cases with connectors for switching.
- Interrupter PT-1 provides:
- enabling and disabling of current of underground communications cathodic protection on the temporary step synchronized by signals of the satellite GPS/GLONASS system;
- the built-in clock synchronization, at loss of signal GPS/GLONASS;
- digital display of all parameters on LCD display;
- programmable operating time.
