Control Circuit Transformer

Listing ID #1461907

We bring forth Control Circuit Transformer with basically electric components fitted on the Circuit boards which are then fitted in the Junction boxes and are used in the monitoring of the current passed on to the Oil pipelines, Tank farms and Oil wells to avoid disruption of the flow of the Oil and Gas. A Control Circuit Transformer is a device designed to provide a reduced control voltage for energizing the coils of electromagnetic devices such as motor starters, contactors, relays, & electronic circuits. These devices make up the majority of the loads supplied by the Control Circuit Transformer. Control Circuit Transformer is also referred to as Industrial Control Transformers, Machine Tool Transformers, and Control Power Transformers, Inrush Volt-Ampere & Sealed Volt-Ampere considerations. The proper size, or the VA rating, of the Control Circuit Transformer is important. It will be a determining factor in the life of the transformer, which ultimately will reflect on the proper operation of control devices that it supplies. 
Methods of Selecting
The methods of selecting transformer VA ratings addressed in this technical paper are applicable to 50-3000 VA. Control Circuit Transformer. The transformers used in this application fall into the dry type insulation category. Typical primary voltages are 600, 480, 240, and 110. Transformers can also be manufactured with special primary & secondary voltage combinations. There are two VA values to be considered when selecting a transformer. Energizing electromagnetic components creates a large momentary surge current, commonly referred to as inrush VA. This is the first VA value to be considered. The inrush VA will last approximately 5-20 milliseconds and can have a value as high as ten times the transformer's nameplate rating. Thus, the inrush VA will be high in value and short duration. A properly selected control circuit transformer is designed to handle the momentary inrush VA and at the same time maintain a secondary voltage within a set range. The second value to be considered is the sealed VA, the amount of volt-amperes required to maintain the energized state of an electromagnetic device. This VA requirement will be 5 to 10 times less than the inrush VA.
