Substation Technical Requirements Sample Clauses
The Substation Technical Requirements clause defines the specific technical standards and criteria that must be met in the design, construction, and operation of a substation. It typically outlines requirements such as equipment specifications, safety protocols, performance benchmarks, and compliance with relevant industry codes. By clearly establishing these technical expectations, the clause ensures that the substation will function reliably and safely, minimizing the risk of operational failures and regulatory non-compliance.
Substation Technical Requirements. It should be highlighted that, during the development of the final project study, the Concession Holder shall carry out all the studies required to ensure the proper operation of the equipment of the system proposed.
Substation Technical Requirements. The power transformer shall be supplied with current transformers incorporated into the bushing insulators, with three (3) 5P20 protection cores, for the three phases, in the three windings, as well as the corresponding cores for thermal image regulation and protection. The nominal voltage, voltage regulation, and 138/22.9 kV transformer connection group shall be as follows: ▪ Voltages - Primary voltage 138 kV - Secondary voltage 22.9 kV - Tertiary voltage 10 kV ▪ Rated power 20 – 25 / 20 – 25 / 6-7.5 MVA (ONAN – ONAF)(*) ▪ Connection Group YN/YN/Delta - Primary side, 138 kV Wye, solidly grounded neutral - Secondary side, 22.9 kV Wye, solidly grounded neutral - Tertiary side, 10 kV Delta ▪ Voltage regulation Automatic under load on the 138 kV side, with taps of +/- 10 x 1% (**)
Substation Technical Requirements. The reactors shall be supplied with current transformers incorporated into the bushing insulators, phase side and neutral side, with two (2) 5P20 protection cores, as well as the current transformers in the neutral of the three-phase setup. The reactance and power values and the definitive characteristics of the equipment shall be determined by the CONCESSIONAIRE, as defined, supported, and approved in the POS. Loss levels shall be guaranteed in transformer for permanent load levels of 100%, 75%, and 50% of the rated power. For the reactor, the loss value shall be guaranteed for operation at the rated voltage. The guaranteed values shall meet IEC 60076 or its ANSI/IEEE equivalent.
