GC–TRANSFORMER OIL GAS ANALYZER
Sl. No. 1.
Description: Transformer Oil Gas Analyzer (TOGA)
No. of Units Required: 1
Desired delivery: Within Months from the date of the issue of the Purchase Order.
Destination: ETD Laboratory, EWA/ Bahrain

Gas Chromatograph with Electronic Pneumatic Controls, appropriate injectors & detectors, Injection Ports with gas saver mode, Columns, Methanizer, headspace auto sampler, accessories and spares along with Data management system as required. System should have facilities for the operation of at least two injectors, two detectors simultaneously.

SAMPLE PREPARATION SYSTEM
The system must be optimized for the sample preparation of transformer oil for DGA (Dissolved Gas Analysis) with Head Space technique. The system should be compact, easy to handle and should have the facility for enhanced sample storage delay (at least two weeks). The system should be such that all the manual procedures required for sample preparation are performed (dosing of the sample, positioning of the sealing plug and sealing of the vial) in an inert gas atmosphere (gas must have lower solubility characteristics in oil). The system operation should be in a controlled ambient for ensuring a good repeatability of sample preparation, minimal interferences from air gases (O2, N2, CO2) and a controlled flow of the inert gas.
