AVR Astatic operation

AVR Astatic operation

AVR Astatic operation

(OP)
Can anyone throw any light on the term "astatic" when used to describe a mode of AVR operation.

RE: AVR Astatic operation

The term astatic control means that the droop CT is connected in such a way as to provide normal generator regulation when running in parallel with another supply.

Suggestion: Visit

for:
6.2.2 ASTATIC CONTROL
The 'droop' current transformer can be used in a connection
arrangement which enables the normal regulation of the generator to be maintained when operating in parallel.
This feature is only supplied from the factory as a fitted droop kit,however, if requested at the time of order, the diagrams inside the back cover of this book will give the necessary site connections. The end user is required to provide a shorting switch for the droop current transformer secondary.
With the MX321 AVR this accessory is supplied loose for fitting in the control panel.
In the case of the SX421 the cricuit breaker is always supplied and will normally be fitted in the generator.
Important ! When the circuit breaker is supplied loose,
the AVR is fitted with a link on terminals
K1-K2 to enable operation of the AVR.
When connecting the circuit breaker this
link must be removed.
