Only basic continuity and resistance checks are possible: winding resistance, open/short detection, and bushing continuity. Full diagnostic requires specialized equipment.

The power rating of a transformer describes how much apparent power (kVA or MVA) it can continuously deliver without exceeding thermal limits. It depends on conductor size, core cross-section, insulation class, cooling system, and allowable temperature rise. The rating ensures that both copper losses and core losses remain within design limits under nominal voltage and frequency. In power systems, ratings are often expressed in MVA to reflect the role of transformers in transferring apparent power between voltage levels without changing total system power.

SF6-insulated transformers are used where space constraints, safety, or environmental sealing are critical. SF6 offers high dielectric strength and arc-quenching capability, enabling compact HV equipment for urban substations.

Power company transformers, mainly distribution and substation units, step voltage down from higher distribution levels (e.g., 11-33 kV) to residential and commercial service voltages. They provide isolation and help limit fault currents. By adapting voltage to end-user needs, they enable efficient bulk transmission at higher voltages while ensuring safe delivery locally. They also play a role in voltage regulation and power quality, often integrating with capacitor banks and feeder automation for modern smart grid operations.

In PMB practice, the most common plasticizers are aromatic process oils, naphthenic oils, and heavy vacuum distillates, sometimes also flux oils from refinery streams. Their main benefit is to reduce the viscosity of the base bitumen and improve polymer swelling, which shortens curing time and improves dispersion stability. Good plasticizers also enhance low-temperature flexibility and reduce the risk of phase separation during storage. The key is compatibility: the oil must have good solvency for both bitumen maltenes and the polymer, otherwise it can actually ???????? storage stability instead of improving it.

TOR-5 is not limited to mineral oil only – in principle it can also be used with synthetic and natural ester fluids, but with some important considerations. The main difference is that esters have much higher water solubility and different moisture equilibrium behavior, so sensor calibration and alarm thresholds must be adapted. Moisture in ppm has a very different meaning in esters than in mineral oil. Hydrogen and temperature monitoring work the same way, but interpretation of trends must follow ester-specific standards. So the system is suitable, but it requires proper configuration and different diagnostic criteria.

In normal operation, the TOR-5 works in a continuous data acquisition mode, but continuous permanent connection to the central server is not strictly mandatory. The local controller constantly measures and logs parameters, while data transmission to the server is usually periodic, for example every few minutes. If communication is temporarily lost, the system stores data locally and uploads it once the connection is restored. This architecture improves reliability and avoids data gaps, while still allowing near real-time monitoring on the server side.

The UVB-2 plant performs modification of bitumen with SBS, EVA, or crumb rubber. It includes high-shear mixing, temperature control, and inline homogenization.
