SIPLUG® Online 3 has been designed for use inside the Plug-In units of the switchgear of Nuclear Power Stations. The purpose of this module is the measurement of active power for assessment of electrical and mechanical characteristics of actuators and valves. All necessary parts for the measurement are integrated in the Plug-In unit with minimum maintenance requirements.
SIPLUG® Online 3 can be integrated in the plant’s computer network (LAN). With this solution all measurement information will be available immediately in the offices of plant engineers. Features - measurement function triggered by operation of solenoid
- Automatic signal evaluation for each measurement with data assessment and comparison with limit values
- Automatic storage of measurement and evaluation result on a server for trending and statistic purposes
TheSIPLUG® Online 3 System is available for motor operated valves as well as for permanent monitoring of solenoid operated valves.

The SIPLUG® Online 3 module has been
optimized for the integration in switchgear
plug-in units. A small power supply for the
diagnosis unit is alsointegrated and connected
to one of the three phases. For service
purposes and maintenance of the module an
interface to a PC is available. A special service
adapter can be used to indicate the current
state of the module. For the measurement intrinsically safe current
and voltage transformers are installed. All
necessary signals for the diagnosis are
galvanic isolated and decoupled by the
transformers. The current and voltage signals are digitized
and stored in the controller module after the
internal calculation of the RMS values and of
the active power. Measurements up to 350
seconds are stored in the module even during
a failure of network or power supply. |
