After a new installation or overhaul, the generator should be short-circuited. The purpose is to measure the coil loss of the generator, that is, to measure the copper loss. Before the generator is subjected to the short-circuit test, the following conditions must be met:

(1) The generator stator cooling water is normally put into operation;

(2) The hydrogen pressure in the generator reaches the rated value and the hydrogen cooling water is normally put into operation;

(3) The generator outlet is short-circuited by a dedicated short circuit;

(4) The excitation system can guarantee a slow and uniform boost from zero.

ETH Miner

Mining is the process of creating a block of transactions to be added to the Ethereum blockchain in Ethereum's now-deprecated proof-of-work architecture.

The word mining originates in the context of the gold analogy for cryptocurrencies. Gold or precious metals are scarce, so are digital tokens, and the only way to increase the total volume in a proof-of-work system is through mining. In proof-of-work Ethereum, the only mode of issuance was via mining. Unlike gold or precious metals however, Ethereum mining was also the way to secure the network by creating, verifying, publishing and propagating blocks in the blockchain.

Mining ether = Securing the Network

Mining is the lifeblood of any proof-of-work blockchain. Ethereum miners - computers running software - used their time and computation power to process transactions and produce blocks prior to the transition to proof-of-stake.
