Magnetic Oil Level Gauge Troubleshooting: Common Problems, Causes & Solutions

The significance of transformer oil in insulation and heat dissipation cannot be overstated. Thus, it is critical to ensure the right amount of oil in the tank to keep the transformer working effectively. To track the level of oil in the conservator of the transformer from outside the oil tank, operators can use a Magnetic Oil Level Gauge. 

A Magnetic Oil Level Gauge may not function properly if it is not installed correctly and is subject to mechanical failures or oil leaks. Understanding the common malfunctions associated with the device can help the maintenance team determine the cause of such issues and take the necessary steps to solve them.

What Is the Magnetic Oil Level Gauge?

The Magnetic Oil Level Gauge can be defined as a device that indicates the level of oil inside an oil-filled transformer. It is typically placed on its conservator and operates via a float type of mechanism that reports the changes in the level of oil inside the device.

The internal float moves because of the variations of the oil level. By means of a magnetic element, the float movement is transferred to an external pointer, which shows the oil level.

The main advantage of this device is that it allows performing transformer monitoring externally, making the process simple.

Frequent Problems of Magnetic Oil Level Gauges

A Magnetic Oil Level Gauge can malfunction in different ways depending on the operation conditions, installation technology, and maintenance practice. Some common issues are given below.

1. Pointer Not Moving

One very serious issue is when the Magnetic Oil Level Gauge needle is immobile while the oil level is changing.

In this case, it is possible to say that either the internal float is stuck or the devices are out of order. However, before concluding that the gauge is malfunctioning, the maintenance department must make sure that the oil level has changed.

If the oil level has changed but the needle is still in the same position, the Magnetic Oil Level Gauge must be serviced in accordance with the instructions provided by the manufacturer.
