State-of-the-ArtTransformer Protection Manufacturer Offering Top Quality atWholesale Prices Why Transformer Protection Needed? Transformers are a critical and expensive part of most power systems. Due to the long lead time for repair or replacement of transformers the major goal is to have protection and limit the damage to a faulty transformer. Some of the available protection devices protect against such things as overexcitation and temperature rise that could cause transformer failure. The more critical the transformer is to the operation, the more comprehensive the protection needs to be and will need multiple function protective relays and other protection devices. Types of Transformer Protection The type of protection varies depending on the application and the importance of the transformer. The most common protection is against faults and overloads. These protection devices should minimize the time of disconnect and reduce the risk of catastrophic failure. Any extended operation as faults or overloads compromises the life of the transformer. These protection devices provided quicker isolation of these problems and helps to protect and extend the life of the transformers. Common Causes of Transformer Failure Are Reasons to Add Transformer Protection Transformer failures usually can be classified as following: Winding failures which are due to short circuits including turn-turn faults, phase-phase faults, phase-ground, and open winding. Core faults which includes core insulation failure and shorted laminations. On-load tap changer failures are usually caused by mechanical, electrical, short circuit, overheating. Terminal failures such as loose connections, open leads, and short circuits. Abnormal operating conditions such as overloading, overvoltage, and over fluxing External faults. Choosing Transformer Protection For Your Application The engineer has to balance the expense of a particular protection scheme or sacrificing the transformer. There are no rules or regulations determining what the appropriate protection scheme is for a transformer application. Call one of our transformer protection specialists for assistance in reviewing the transformer protection options and selecting the one that meets your need and budget. There is a tendency to tie protection to the MVA and primary kV of a transformer. Some of these issues to consider are the severity of personnel safety concerns, and the danger to nearby structures if the transformer tank ruptures with an oil fire. Transformer Protection Equipment Save Cost By Reducing Downtime The engineer also needs to consider the economic impact if the transformer fails and how downtime for repairing or replacing the transformer will impact the organization. The impact of production time loss, and the different costs related to repair time vs. complete replacement time. Does your organization have the availability of backup power or emergency replacement transformers, and the cost of each of these options. A transformer protection scheme can reduce or change a replacement into a repair. Call Our Transformer Protection Specialists Today!
