Transformer Installation

Transformer Installation - Some Best Practices

There are many problems that can be avoided during transformer installation simply by installing the transformer in the correct environment. Many difficulties and safety hazards can be avoided or minimized by keeping certain factors in mind while positioning a transformer, before it is set up and connected. Likewise, the location can have a bearing on how the transformer should be set up, and what precautions should be taken in the future.

Transformer Installation

The Standards

Installing transformers in accordance with the ANSI, NEMA, and IEEE standards is critical to ensuring a safe electrical installation as well as a reliable power supply system - especially for those applications where power quality is an issue. Transformer installation is one of the most common-yet-complicated installation practices that are cause for considerable confusion when sizing Over Current Protection Devices (OCPDs) and bonding and grounding conductors.

Many electrical installations can be a challenge in terms of NEC requirements, and transformers can raise that challenge to a new level. A properly designed installation will ensure the conductors and equipment are properly sized, protected and also deal with the overriding issue of grounding. Incorrect installation can lead to fires from improper protection or conductor sizes, as well as electric shock from inadequate grounding.

This article will provide a brief overview of important considerations to keep in mind during installation, of transformers located outdoors and indoors, and for dry-type vs. liquid-filled transformers.

Transformer Installation

Installation Best Practices Some of the particularly important transformer installation best practices are listed below:

1. Permanent Grounding: Once the transformer is placed permanently - before further inspection is carried out and before assembling the unit - the tank should be permanently grounded with a correctly sized and properly installed permanent ground.

2. Humidity: No access should be permitted to the transformer liquid-filled compartment in conditions of excessive humidity or rain. If humidity exceeds 70% for example, dry air should be continuously pumped into the gas space. Liquid-filled transformers that are shipped with Nitrogen in the gas space must be purged by pumping dry air for at least 30 minutes before service personnel can enter the tank. Oxygen concentrations of 19.5% to 23.5% are advised.

3. Fluid Inspection: If the insulating liquid for inspection needs to be drawn down, make sure you have equipment for clean and dry storage of the liquid during inspection and for filtering the liquid prior to refilling the tank. It is very important that all associated equipment used in the handling of the fluid (hoses, pumps, etc.) are also very clean and dry. If this equipment was used before with a different type of fluid, clean all contaminated items. When you remove the liquid, its level should not go below the top of windings.

4. Pressure Maintenance: Liquid-filled transformers may be stored outdoors upon delivery. Sufficient gas pressure must be maintained to allow a positive pressure of 1 psi to 2 psi at all times, even at low ambient temperature. The pressure-vacuum gauge, if supplied with the transformer, will show pressure variations with ambient temperature. Pressure and ambient temperature readings should be recorded regularly. The manufacturer's instructions must be referred to for storage of accessories.

5. Inspection and filling: You should make a final inspection of the transformer before it is energized, particularly if any work has been done inside the tank. All electrical connections should be checked for tightness. All bushings should be checked for tightness of gaskets, and all draw lead connections should be checked. Electrical clearances inside the tank should be checked. One final check should be made to ensure all tools have been removed.

6. Loading: After applying full voltage, the transformer should be kept under observation during the first few hours of operation under load. After several days, check the oil for oxygen content and dielectric strength. All temperatures and pressures should be checked in the transformer tank during the first week of operation. Except for special designs, transformers may be operated at their rated kVA if the average ambient temperature of the cooling air does not exceed 86'F (30'C) in any 24-hr period, and the altitude does not exceed 3300 ft.

7. Surge arresters: When used, surge arresters must be installed and connected to the transformer bushings/terminals with the shortest possible leads. These arresters may be necessary to protect the equipment from line switching surges and lightning.

When the Transformer is Under Vacuum, Never,Never...

* Apply voltage to the transformer

* Leave it unattended; a positive pressure must be applied

* Stand or walk on the transformer tank

8. Structural Considerations: Multiple transformers can be mounted on a single pole as long as the weight is evenly distributed, and the total weight is well within the safe limits of the pole, any cross-arms or supporting bolts.

9. Mounting: Sub-100 kVA single-phase distribution transformers are typically mounted above the secondary mains. Platform or pad mounting are options for transformers larger than 100 kVA.

10. Protection: Apart from self-protected transformer types, all distribution transformers must have lighting arresters and fused cutouts installed on the primary side.

11. Ground wires: Cover all ground wires with plastic or wood molding to a point 8 feet above the base of the pole.

12. Guying of poles: Correctly installed guy wires can protect the pole line from damage caused by the strain of the line conductors and pole-mounted equipment, and minimize pole line damage caused by severe weather.So most important of Transformer Installation.
