A standard diesel purification unit can easily clean dyed diesel fuel by removing water and solid contaminants, but it will not remove the dye itself. The dye is a fully dissolved chemical component of the fuel and cannot be separated by filtration or vacuum treatment. To actually remove the color, special adsorption or chemical processes would be required, which are outside the scope of normal fuel cleaning equipment.

It reduces medium-voltage distribution feeders to residential low voltage for safe utilization.

In distribution systems, common transformer bank types include three single phase transformers connected as a three phase bank, often in delta delta, delta wye or wye delta configurations, and single three phase distribution transformers with all windings on one core. Other bank configurations involve open delta for emergency or reduced capacity operation, and special arrangements like Scott connections for two phase to three phase conversion. When someone asks this question, they usually want to distinguish between three single phase units in a bank and one integrated three phase transformer.

Distribution transformers emphasize voltage regulation at LV/MV and are optimized for variable load profiles. Power transformers handle HV/EHV levels, bulk transfer, and grid stability. Grid design relies on proper segmentation for protection, tap control, and redundancy.

Sizing considers peak kVA, PF, ambient temperature, cooling class, and contingency capacity.

Percentage impedance indicates voltage drop under full-load current and defines the transformer’s short-circuit current capability. It is crucial for fault studies, protection coordination, and parallel operation.

It indicates the integrity of insulation between windings and core/ground. Using megohm measurements at defined test voltages, the test detects moisture, carbon tracking, or breakdown paths. Insulation resistance trending helps identify aging before critical failure and is common during commissioning, outages, and post-fault diagnostics.

In the «old oil drain» mode, the CMM-G uses a vacuum pump to extract used lubricant from the wind turbine gearbox into the onboard waste oil tank. This vacuum extraction ensures that oil is removed efficiently from all accessible cavities and passages, reducing the risk of leaving degraded oil behind, which could otherwise contribute to increased wear or contamination after a new oil fill.

Modern LFD units include several built-in safety layers to prevent overheating and abnormal operation. The most important are multiple independent temperature sensors installed on different windings and structural parts, with automatic power reduction or shutdown if any limit is exceeded. Current and voltage are continuously monitored to avoid overcurrent conditions. In addition, there are software interlocks, emergency stop circuits, and alarms for loss of vacuum or cooling. These protections ensure that heating remains uniform and that any abnormal trend is detected early before it can damage the insulation.

Yes, adding a vacuum module makes real degassing technically possible, but with important limitations. In that configuration, TOR-5 no longer works only as a conditioner, but as a low-capacity online degasser: oil is circulated through a small vacuum chamber where dissolved gases are released. This is effective for gradual hydrogen and air removal during long-term operation. However, it cannot replace a full-scale vacuum oil processing unit for fast deep degassing after major faults or oil filling. It is a stabilization tool, not an emergency treatment system.
