Oil analysis | Oil service | Oil sampling

This is what we understand by oil analysis service: Take an oil sample, apply the oil sampling set and then use it for analysis. The transformer insulating oil analysis starts with the correct procedure of oil sampling according to DIN EN 60422. For oil analysis it is important to select the appropriate oil sampling set. Whether aluminium bottle or glass syringes in a transport case, the oil samples are selected according to the analysis requirements. Standardized procedures such as Gas-in-Oil Analysis for the condition assessment of transformers.

The oil samples are the DNA of a transformer. There are some key gases that we look for in a dissolved gas analysis (DGA). Some other tests are also performed such as dielectric breakdown voltage, acid neutralisation number, interfacial tension or water in insulating liquids to name a few. Therefore, oil sampling must be carried out carefully

Viscosity and purity tests are important for checking lubricants. At your request, we assess operating fluids such as lubricants, oils, insulating oils, turbine oils, coolants and hydraulic oils. The oil analysis to be carried out does not end with the test results. If desired, you will receive solution-oriented assistance from us.

DC Ground Fault | GFL1515 | Battery Ground Fault

Battery Ground Fault | Battery Check
GFL1515: Essential for Detecting DC Ground Faults in DC Systems

The GFL1515 is an essential measuring device for detecting DC ground faults in various DC systems. This GFL1515 Detector is crucial for identifying faulty grounding, especially where electrical cables are damaged or show leakage to the ground.

Fault Detection Through Signal Injection

The GFL1515 detects unintentional DC ground faults by injecting a low-frequency signal into the faulted polarity. Using current clamps and a portable receiver, operators can follow this signal to pinpoint the physical location of the DC ground fault.

Online Measurements with High Voltage Tolerance

The GFL1515 enables measurements even in online DC systems. While the device’s output current remains low, its output voltage can reach up to 1000V, allowing it to function safely without interference. Per the NERC PRC 002-6 standard, the battery and DC power system must be checked for unintentional grounding every four months. If a ground fault is found, the GFL1515 allows for precise fault localization without disconnecting the live circuit.

Method for Fault Localization

The GFL1515 uses several methods to locate faults accurately, based on these principles:

Signal Generator and Return Circuit

The signal generator connects to the DC system with two test leads, injecting a low-frequency current signal. This signal flows through the circuit, exits at the faulted grounding point, and finally returns to the generator. This return circuit assists in signal tracing in the next step.

Signal Receiver for Directional Tracking

The signal receiver tracks the signal’s direction, which always points toward the fault. Using one clamp on two busbars, or two clamps on separate busbars, the device works efficiently with strong anti-interference capability, even in online systems.

Signal Strength and Phase Angle Changes

The strength and phase angle of the signal change significantly before and after the grounding fault. These changes help pinpoint the exact fault location with accuracy.

Oil Testing | DÖPEV | Oil Sampling Control

Oil testing in systems | Oil testing | DIN EN 60422

DÖPEV – the display oil sampling device with a twist for oil sampling according to DIN EN 60475 (VDE 0370-3).

Failures due to faulty transformer oil analysis can lead to negative and detrimental developments. They can evidently have serious effects on the power supply and the service life of the transformer. Sampling the oil from oil-filled transformers in operation is an efficient method for determining the condition of the solid and oil insulation. In addition to that, it provides information about the operating condition of the transformer.

And it does so without having to open or deactivate the transformer. Improper oil sampling or contamination can have an immense influence on the measured values of the individual test methods. Ultimately, this can lead to false conclusions about the quality of the insulating liquids. To ensure consistent performance and long transformer life, regular oil testing in installations is essential.

Taking oil samples without contamination
The overall aim is to remove the oil from a transformer without contamination. To further carry out an oil test in the laboratory and analyse the sample. Your result of the “gas in oil analysis” or the other “dielectric measurement methods” can only be as good as you have taken your oil sample. With the new oil sampling system DÖPEV you take the oil sample free of contamination. As well as according to the standard and without contact with the outside air.

ÖPEV-k and DÖPEV: undoubtedly the perfect oil analysis set

These periodic examinations are generally an important part of the maintenance of transformers for a safe power supply. Not only the sampling, but also the handling of the oil sample plays a major role. Sampling and handling are made very easy and effective with the ÖPEV-k and the DÖPEV. Basically, this allows you to carry out an insulating oil test in no time at all. The ÖPEV-k oil sampling device guarantees absolute ease of use for safe oil sampling from oil-filled transformers. In combination with the DÖPEV display oil sampling device, oil sampling becomes even easier.

By means of three ball valves on the DÖPEV you can regulate the oil sample. Furthermore, you can constantly control the temperature of the oil. The oil analysis device DÖPEV can be connected to the oil drain device ÖPEV-k and creates the perfect oil analysis set. With this set you can take the oil sample from the transformer comfortably and contamination-free. And in the next step, transport it to the oil test in the laboratory.​

Distribution transformers | ÖPEV-k | Transformer oil drain tap

Distribution transformers | Transformer oil drain tap

Oil filled distribution transformers are a very important part of the power supply, regardless of their size. By performing targeted inspections, maintenance, and servicing, it is possible to extend their service life. However, to properly analyze the contained insulating oil and draw a possible diagnosis, it is necessary to extract the oil correctly. If the insulating oil the transformer contains is faulty, this can in fact lead to serious consequences.

ÖPEV-k oil drain device for transformers

This therefore means that accurate results of insulating oil analysis are critical to the condition of the transformer. The results of an oil sampling additionally determine the further course of action with the oil transformer. In general, the ÖPEV-k is ideally suited for oil sampling, namely on an oil local network transformer. Or on distribution transformers that have a difficult or poorly accessible oil drain valve. On some transformers it is very complicated to take an oil sample. For example, on concrete or complete stations.

But ÖPEV-k guarantees absolute ease of use for safe oil sampling at the transformer. Adapters for the nominal width 22 NW and 31 NW are available as accessories. Consisting of stainless steel, the ÖPEV-k and the adapters thus come in a robust and compact design. The oil drain device ÖVEP-k is screwed onto the drain tap of the transformer with the adapter (for example NW 22). The shaft is then used to open the drain valve of the transformer and the ÖVEP-k fills with oil.

In total, there is an oil sampling tap and a vent valve on the ÖVEP-k. Consequently you can connect a hose to the oil transformer drain tap of the OVEP-k to remove the oil sample without contamination. WGM Support also offers a remote sampling kit to control the oil sample. In summary, the ÖPEV-k is the ideal and indispensable tool for effortless oil draining from oil distribution transformers.
