VFD Control

VFD control is how a variable frequency drive is controlled.  A variable frequency drive is basically a system that is used for controlling the rotational speed of an alternating current motor.  VFD control is controlling the frequency of the electrical power that is supplied to a motor.  There are several vfd controls used in the electrical industry and TEMCo is a huge supplier and manufacturer of such vfd controls.  TEMCo carries brands like Teco Westinghouse, Magnatek, Yakawa, Safetronics, Honeywell and many more quality vfd control products.  Call TEMCo today at 510-490-2187 for the latest technology on vfd control.

Types of VFD Control

When looking for a good quality vfd control, many avenues are considered such as:

VFD speed control; basically controls the rotational speed of a motor

VFD motor control;  can be a three phase induction motor or a single phase but three phase is preferred

VFD pump control; controls the number of pumps and the varying of speed to the pump 

VFD vector control; there is open loop and closed loop that obtains feedback information that calculates the exact vector of voltage and frequency and then tells the motor what to do 

VFD fan control; used to control and regulate airflow on signal or multiple fans

VFD torque control; when the torque limit is set - used with devices such as clutches, gearboxes, etc.

Indoor & Outdoor Pad Mount Transformers

Enclosure options for pad mount transformers are available in indoor (NEMA 1), outdoor (NEMA 3R, 4 and 12) and come in many different configurations in regard to connection and access types.  Pad mount transformers for indoor use under most circumstances, must be of dry type construction. For out door applications oil filled pad mount transformers are acceptable when required.

Common Pad Mounted Transformer

Most people see pad mounted transformers everyday in their neighborhood or their businesses; they are the green square boxes you see everywhere.  A Pad mount transformer is  mounted on a pad foundation with high and low tension cables coming directly into the terminal compartments which are part of the transformer housing.

Pad Mounted Transform Sizes

Pad mounted transformers come in various sizes and can be placed underground as well.  Three phase pad mounted transformers range in sizes from 75kVA up to 5000kVA with voltages ranging from 2,400 up to 34,500 delta or wye.  Low voltage pad mounted range in size from 208y/120 through 24,940y/14,000.

Pad Mounted Transformer Applications:

 Manufacturing facilities
 Refineries
 Office buildings
 Schools
 Hospitals,
 Residential
 Restaurants
 Retail stores
 Warehouses

Pad Mounted Transformer Purchasing Guidelines

When purchasing a pad mounted transformer there are a few guidelines that you need to follow. Pad mounted transformers should have superior insulation and a quality sealing system. They should meet or exceed the ANSI/IEEE test standards C57.12 and C57.12.90 and other international standards.  Pad mounted transformers need built to be in a sealed-tank oil preservation system which protects the interior from the environment.  The outside should have electrostatically applied powder paint finish, often with a green polyurethane top coat.  For security reason they should have a three-point latching door on all pad mounted transformers.

Pad Mounted Transformer Placement

On placement of a pad mounted transformers you will have to check with the local county and city ordinances for guidelines.  Common restrictions are that the front of the transformer must be free of any obstructing material so that it is clearly visible and the top of the transformer must be completely unobstructed.  Plants and fencing can be placed around the two sides and back of the transformers but you will have to provide a 3 foot clearance.  Do not put pad mounted transformers near trees, because trees planted within 15’ of the transformer may require removal if tree roots or foliage hinder service or maintenance of the transformer.
When purchasing a pad mounted transformers always make sure that they are made with high-grade materials, combined with an engineering-design system that will provide you with years of high-reliability service.
