What Is a Transformer Conservator Tank?

2026年10月24日 16:50:26

A transformer conservator tank is an auxiliary oil reservoir connected to the main tank of many oil-immersed transformers to accommodate oil expansion and contraction as temperature changes. Oil mo...

What Is a Transformer Pressure Sensor?

2026年10月24日 16:30:07

A transformer pressure sensor measures pressure in a transformer oil or tank-related system and converts the pressure condition into a usable measurement signal. Pressure data can help indicate cha...

What Is a Transformer Oil Level Indicator?

2026年10月24日 16:21:23

A transformer oil level indicator shows the level of insulating oil in an oil-immersed transformer, commonly in the conservator tank. Oil level changes naturally as transformer oil expands and cont...

Wie lässt sich die Temperatur von Hotspots in den Wicklungen eines Ofentransformators überwachen?

23. Oktober 2026, 14:57:45 Uhr

Furnace transformer hot-spot monitoring should focus on winding temperature under high-current and cyclic loading, not only on tank or top-oil readings. Fiber optic sensors measure temperature dire...

Was ist ein Buchholz-Relais in einem Transformator?

23. Oktober 2026, 12:14:12 Uhr

A Buchholz relay is a gas- and oil-operated protection device installed in the pipe between the main tank and conservator of suitable oil-immersed transformers. Slowly developing internal faults ma...

Wie funktioniert eine Druckentlastungsvorrichtung (PRD) für Transformatoren?

23. Oktober 2026, 10:49:26 Uhr

Transformer PRDs open when abnormal internal tank pressure reaches the designed operating point of the device. Releasing pressure through the device helps reduce mechanical stress on the transforme...

Was ist eine Öltemperaturanzeige in einem Transformator?

23. Oktober 2026, 10:34:13 Uhr

Oil temperature indicators (OTI) measure and display the temperature of the insulating oil in a transformer, normally the top-oil temperature. OTI instruments are mainly used on oil-immersed transf...

Checkliste für die vorausschauende Wartung von Transformatoren

14. Oktober 2026, 15:16:15 Uhr

Winding and hot-spot temperature trends, read against load, ambient temperature and cooling status. Dissolved gas trends and gas rate of change in oil-immersed transformers, not single oil samples....

Wie wählt man einen Temperatursensor für Transformatorwicklungen aus?

12. Oktober 2026, 17:07:10 Uhr

Transformer winding temperature sensors should be selected according to transformer type, measurement location, voltage environment and whether direct hot-spot measurement is required. Fiber optic ...

Leitfaden zur Alterung von Transformatoren

11. Oktober 2026, 16:19:08 Uhr

Transformer ageing is the gradual deterioration of a transformer's insulation, mainly the cellulose paper around the windings, under thermal, chemical, electrical and mechanical stress. Winding hot...

Wie lässt sich die Kühlleistung eines Transformators überwachen?

11. Oktober 2026, 15:54:35 Uhr

Transformer cooling performance is monitored by comparing winding temperature, top-oil temperature and transformer load with fan, oil pump and cooling-stage status over time. Winding temperature an...

Was ist die Transformator-Diagnostik?

11. Oktober 2026, 15:26:36 Uhr

Transformer diagnostics is the process of using test results, monitoring data and fault indicators to judge the present condition of a power or distribution transformer and to narrow down the likel...

Was ist ein Transformatoralarm?

11. Oktober 2026, 12:42:00 Uhr

Transformer alarms warn operators when monitored temperature, dissolved gas, oil, pressure, insulation, bushing, OLTC, cooling or device conditions reach configured limits or abnormal states. Warni...

Cloud-basierte vs. lokale Transformatorüberwachung: SCADA, Fernzugriff und Datenarchitektur

9. Oktober 2026, 16:52:40 Uhr

Local transformer monitoring keeps data, alarms and protection logic inside the substation or plant, while cloud-based monitoring sends selected data to a hosted platform for remote access and flee...

Überwachung von Transformatoren in Rechenzentren: Temperatur, Last, DGA und Alarmstrategie

9. Oktober 2026, 16:48:12 Uhr

Data center transformer monitoring protects the power chain that feeds UPS systems, cooling plant and IT loads, where an unplanned transformer outage can interrupt an entire hall. Most in-building ...

Überwachung der Transformatorisolierung: Was lässt sich online überwachen?

7. Oktober 2026, 15:54:38 Uhr

Measurable online: dissolved gases (DGA), moisture in oil, partial discharge (PD), bushing capacitance and tan delta, winding hot-spot temperature and core/clamp ground current. Estimated online: m...
