A worthwhile investment – triple certainty
Arc sensors are used to monitor the occurrence of arcs in the transformer compartment. They ensure that a Wind Turbine Generator System (WTG) is safely switched off in the event of an incident. Arcs can, however, also occur in the control cabinet of the circuit breaker – with the risk of a fatal fire. The cause: The overcurrent release in the medium-voltage switchgear is delayed when an arc occurs. As a result, considerable damage can generally not be avoided.
In order to effectively prevent such hazards, Availon - the worldwide leading multibrand provider of WTG services – has lauched an arc sensor as a new upgrade for turbines of type Vestas® V80 VCS®, V90 2.0 MW and V66. The arc sensor is installed near the circuit breaker for monitoring the copper rail main distribution. In case of arcing, the turbine is disconnected from the grid within milliseconds.
Availon’s additional arc sensor prevents serious fires or total loss in the copper rail main distribution, thus minimizing the risk of long turbine shutdowns and high costs of a repair of a WTG.
Apart from the arc sensor as its latest upgrade for turbines of type Vestas® V80 VCS®, V90 2.0 MW and V66, Availon recently launched an improved design of the transformer bracket. With the aid of the new design concept, the multibrand service company has succeeded in achieving a permanent stabilization of the transformer against vibrations. Another upgrade, the slipring box suction system, ensures that the graphite dust from the generator carbon brushes moves in an air flow and is effectively transported out of the slipring box. In this way, the risks of considerable damage to the generator due to the graphite causing sparking and the formation of arcs can be sustainably reduced.
The arc sensor and the upgrades “transformer bracket“ and “slipring box suction system“ are available as of immediately. Please contact us for further information by phone on 05971-8025-0, by email on windservice@availon.eu or via our website www.availon.eu.
