Version –302–402/403/404-602.
Areva, Electronic Edition, 2005. — 60 pages.The P139 time-overcurrent protection and control device is a one-box solution for protection and control.
The protection functions available in the device provide selective short-circuit protection, ground fault protection, and overload protection in medium- and high-voltage systems.
The systems can be operated as impedance-grounded, resonant-grounded, grounded-neutral or isolated-neutral systems. The multitude of protection functions incorporated into the device enable the user to cover a wide range of applications in the protection of cable and line sections, transformers and motors. The relevant protection parameters can be stored in four independent parameter subsets in order to adapt the device to different operating and power system management states.
The control functions are designed for the control of up to six electrically operated switchgear units equipped with plant status signaling and located in the bay of a medium-voltage substation (or a high-voltage station with basic topology). The P139 has more than 250 predefined Bay Types stored for selection and it is also possible to load user-defined bay templates.
In software version -602, several new features have been added to the P139 functions.
These will now be described with reference to the P139 manual with print number AFSV.12.06730.
In addition to the software changes, the following new order options have become available:
- Reference voltage transformer for the automatic synchronism check function.
- Designs with ring-terminal connection.
- Rapid-response output module with 4 thyristors.
Two options (with or without angle brackets) are offered for flush panel mounting. The dimensional drawings and required panel cutouts are shown in the Supporting Documents packed with the devices as are the location and terminal connection diagrams.Table of Contents:Overview - Changes in Software Version -602.
