DEIF’s loss of mains relays protect generators against damage

resulting from a non-synchronised reconnection  to the grid

after a temporary mains failure.

A mains failure will be  detected, provided a disconnection at

an arbitrary point of the network results in a swift  change of

the generator frequency (vector shift). An  opening signal is

then transmitted to  the mains circuit breaker, and the generator

will thus be protected against  damages caused by an automatic

reconnection to the high-voltage network.

The APU-4 features all relevant protective functionalities integrated as standard

– simple and easy G59/3 and G99 compliance. The best and the latest check

synchronisation technology is available as an option.

All parameter settings are fully password protected to control access rights.

Featuring an alarm log of up to 150 events, you can analyse faults and prevent

them from reoccurring. Moreover, it automatically carries out a cyclical self-test.

If any errors are found an LED on the front panel and a status output will

indicate it.

With the complimentary PC software download, you can save parameters and

retrieve log data. The software also contains M-logic – a simple-to-use relay logic

compiler. This tool makes it possible for you to customise the application according

to your needs. It is possible to dedicate specific functions or logic conditions to

different in- and outputs.

The APU-4 also features an optional remote, mountable operator panel with a large

display for easy access and reading of values. Among the many reading options you

will find the following: busbar voltage, current, frequency and power factor.

You can attach the display to the basic unit inside the switchboard or mounted on

the front of the switchboard, according to preference.

The optional Modbus TCP/IP communications protocol allows for easy communication

and a number of readout possibilities: remote monitoring for value and alarm readings,

service technician alerts via e-mail or text message, various measurements, etc.

Features

• Complies with G59/3 and G99

• Includes free utility software – available for download

• Modbus TCP/IP communication

• User-friendly display for easy access and value readings

• Fully password protected
