Optimizing Asset Management: PD data provides valuable information for assessing the condition of assets and making informed decisions about maintenance, ukarabati, au uingizwaji.
Matengenezo yanayotegemea Masharti: Shifts maintenance from time-based to condition-based, optimizing resources and reducing costs.

3. Understanding Partial Discharge

Kutokwa kwa sehemu (PD) is a localized dielectric breakdown of a small portion of a solid or fluid electrical insulation system under high voltage stress. It does *not* completely bridge the space between two conductors. PD can be caused by various factors, ikijumuisha:

Voids or Cavities: Small air pockets within solid insulation.
Contaminants: Particles or moisture within the insulation.
Protrusions or Sharp Edges: On conductors, which create areas of high electrical stress.
Cracks or Delaminations: In solid insulation.
Surface Tracking: Discharge along the surface of insulation due to contamination or moisture.

Each PD event generates small, high-frequency electrical pulses, as well as other phenomena like electromagnetic radiation, acoustic emissions, and chemical changes. These signals can be detected and analyzed to assess the severity and location of the PD activity.

4. Online PD Testing Technologies

Several technologies are used for online PD testing:

Transfoma za Sasa za Juu-Frequency (HFCTs): Clamp-on sensors that detect the high-frequency current pulses generated by PD. HFCTs are commonly used for testing cables, transfoma, na switchgear.
Voltage ya Dunia ya Muda mfupi (TEV) Sensorer: Capacitive sensors that detect the voltage pulses induced on the surface of grounded metal enclosures by PD activity within the equipment. TEV sensors are often used for switchgear kupima.
Utoaji wa Akustisk (AE) Sensorer: Detect the ultrasonic sound waves produced by PD events. AE sensors are particularly useful for locating PD sources in transformers and other large equipment.
Masafa ya Juu Zaidi (UHF) Sensorer: Antenna-like sensors that detect the electromagnetic radiation emitted by PD in the UHF range. UHF sensors are commonly used for gas-insulated switchgear (GIS) and transformer testing.
Coupling Capacitors: Used to extract high-frequency signals from high-voltage equipment, allowing for PD measurement.

5. Criteria for the “Bora zaidi” Huduma

8. Maswali Yanayoulizwa Mara Kwa Mara (Maswali Yanayoulizwa Mara kwa Mara)

Ni nini kutokwa kwa sehemu (PD)?

Utekelezaji wa sehemu ni kutokwa kwa umeme kwa ndani ambayo haifanyiki kabisa insulation kati ya waendeshaji. Ni ishara ya uharibifu wa insulation.

Ni nini online PD testing?

Upimaji wa PD mtandaoni ni mchakato wa kugundua na kuchanganua shughuli ya kutokwa kwa sehemu katika high-voltage kifaa kikiwa na nguvu na kikifanya kazi.

Je, ni teknolojia gani tofauti zinazotumiwa kwa majaribio ya mtandaoni ya PD?

Teknolojia za kawaida ni pamoja na HFCTs, TEV sensors, sensorer za utoaji wa akustisk, na sensorer za UHF.

Kwa nini upimaji wa PD mtandaoni ni bora kuliko upimaji wa PD nje ya mtandao?

Upimaji wa PD mtandaoni huruhusu ufuatiliaji unaoendelea na kugundua PD chini ya hali ya kawaida ya uendeshaji, bila kuhitaji kuzima. Jaribio la nje ya mtandao linahitaji kuondoa nishati kwenye kifaa, ambayo inaweza kutatiza na huenda isiwakilishe kwa usahihi hali halisi ya uendeshaji. Jaribio la mtandaoni pia huruhusu ugunduzi wa PD mara kwa mara ambayo inaweza kukosekana wakati wa jaribio fupi la nje ya mtandao.

Upimaji wa PD mtandaoni unapaswa kufanywa mara ngapi?

Mzunguko wa kupima inategemea mambo kadhaa, ikiwa ni pamoja na aina ya vifaa, umri wake, hali ya uendeshaji, na ukosoaji. Mbinu inayotegemea hatari mara nyingi hutumiwa kubainisha masafa bora ya upimaji. Baadhi muhimu mali inaweza kufuatiliwa continuously, wakati wengine wanaweza kujaribiwa kila mwaka au chini ya mara kwa mara.
