На английском языке.The P43x distance protection device is designed for 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, or isolated-neutral systems. The multitude of protection functions incorporated into the unit enable the user to cover a wide range of applications in the protection of cable and line sections, transformers, and motors.
The user can select all general functions individually for inclusion in the device configuration or cancel them, as desired. By means of a straightforward configuration procedure, the user can adapt the device flexibly to the scope of protection required in each particular application. The unit’s powerful programmable logic also makes it possible to accommodate special applications.
The P43x distance protection device is modular in design. The plug-in modules are housed in a robust aluminum case and electrically interconnected via one analog module and one digital module.
In software version -603, several new features have been added to the P43x functions. These will now be described with reference to the P433/P435 manual with print number AFSV. 12.06720.
In addition to the software changes, the following new order options have become available:
- Designs with ring-terminal connection.
- Rapid-response output module with 4 thyristors.
For the P433, designs with an additional voltage transformer input for use with the Automatic Synchronism Check function can be ordered.
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 - P433 Update.
