Transformer Features

This three-phase grounding transformer comes in three-phase configurations with a voltage rating of up to 36 KV on the primary side and 380-415 V on the secondary side. This unit’s cores are made from Grain Oriented Silicon Steel using state-of-the-art technology.

This three-phase transformer is highly energy efficient with lower heat emissions, resulting in fewer cooling requirements. The unit also features mineral oil as an insulating fluid with a 65°C temperature rise.

The Smart Choice

MPS grounding transformers are designed with exceptional quality and attention to detail, meeting a wide range of specifications and applications. These grounding transformers are designed to perform in the most rigorous industries and last for decades. Transformers can be filled with FR3 fluid for added fire safety and prolonged life or with standard mineral oil for typical applications. MPS grounding transformers meet a wide range of commercial, industrial, and utility requirements for both indoor and outdoor installations.

Our portfolio enables utilities, businesses, and infrastructure industries to get the most out of their transformer investments by maintaining a high level of reliability and optimal performance while minimizing life-cycle expenditures and environmental impacts.

Why Are Grounding Transformers Needed?

Grounding transformers establish a ground path for either an ungrounded wye or a delta-connected system. Typically, grounding transformers are employed in the following situations:

They can serve as a metering point for measuring faults.

They help limit the magnitude of transient over-voltages that can occur during a re-striking ground fault.

They may feature a low-voltage auxiliary winding that enables them to function as a local power supply for the substation.

They allow for the connection of phase-to-neutral loads when required.

By providing a low-impedance path to the ground, they can help to maintain the system neutral at or close to ground potential.

They are utilized in wind farms for fault protection on ungrounded cables.

They can provide a source of ground-fault current in the event of line-to-ground faults.
