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 | 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 local network and distribution 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 distribution 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.

Micro Ohm Meter | Ohmmeter

The Micro Ohm Meter DLRO2 is a rugged, portable 2 A micro ohm meter. It delivers fast, accurate and repeatable measurements – even in locations full of electrical noise. The DLRO2 joins a host of products that proudly carry the Ducter™ brand as the latest addition. Ducter™ testers are as well known and proven as Megger insulation resistance testers. Users in the power supply sector or industry get a high level of safety thanks to CAT III-600 V/CAT IV-300 V in accordance with IEC61010. In addition, the device is equipped with self-protection in case of accidental connection up to 600 V without tripping a fuse.

This saves valuable time that would otherwise be spent repairing or obtaining a replacement fuse. When working outdoors, IP54 protection ensures that neither rain nor dust will prevent testing. The DLRO2 is at home in a wide variety of applications, measuring low-resistance values on railroads and aircraft as well as industrial components. Thanks to dedicated long test leads to optimize output, even applications where long test leads are required are no problem for the DLRO2. The long test lead feature delivers up to 1 A of test current into 4 ohms of resistance.

This makes the DLRO2, with its optional test leads on cable reels, the ideal instrument for testing wind turbines and aircraft lightning protection applications. For testing smaller inductive loads, the DLRO2 can apply 2 A for at least 15 seconds, made possible by the integrated high-capacity batteries and a separate inductive load function. The batteries can be fully charged within 2.5 hours, minimizing downtime. Note: The DLRO2 is not intrinsically safe/ ATEX certified and must not be used in explosive environments.

Forklift Battery | Traction battery

BLE 600 is a 3-in-1 device for charging, discharging and activating lead acid or NC batteries. The device is used for forklift batteries. Also for battery charging systems for UPS systems, emergency lighting systems and central battery systems. Due to its small size, the BLE 600 is a handy, portable device. It is applicable to single cells of 1,2V, 2V, 4V, 6V, 8V and 12V. Moreover, the compact device is perfect for regular maintenance of single cells. Especially of old cells.

Three functions of charging, discharging and activating can be used separately or together. This helps the user to maintain forklift batteries while facilitating the overall service. When the charge and discharge functions are used together, the affected forklift batteries are charged and discharged. And this is done in one or more circuits with low constant current. The BLE 600 can even charge or discharge the batteries several times individually.

Activation of the damaged material on the battery electrode plate corrects a caused malfunction of the forklift battery. That way, the battery is regenerated and the forklift battery capacity is increased. As a battery load simulator, the BLE 600 checks the discharge of the battery. In addition, it can use battery capacity tests to determine the actual capacity of battery systems.

Regenerating the forklift battery leads to increase the efficiencies of forklift batteries. Their resources are also effectively utilized. Long-term monitoring of the battery condition can even continuously check the traction battery. Thus, serious damage to the battery is prevented. The device can be operated via touchscreen and keyboard. On top of that, it has a direct USB drive for data transfer to the PC. Software updates can also be made quickly and easily. Users can also download the desired reports in Excel at any time.
