Gas collection device (GCD)

Gas collection device (GCD)


A Gas collection device (GCD) is an accesory of Bucholz relays that is often used in large power transformers. It is connected to the Buchholz relay gas collection petcock, and is used to collect samples of gas and oil from the Bucholz relay easily from ground level. The colour of collected gas is also very clearly visible in the GCD.
 
SS pipes to connect the GCD to the Bucholz relays are also available.
