Definition : Transformers designed to isolate the secondary winding from the primary winding in such a way that neither of the secondary terminals is grounded. Typically the ratio of primary to secondary windings is one to one, so the voltage in the secondary winding is the same as the input voltage of the primary. Isolation transformers are used to reduce the leakage currents of a particular device to levels low enough (e.g., less than or equal to 500 microampere) to meet the upper limits of electrical safety standards. These transformers may be included as an integral part of electric and electronic medical equipment or provided as accessory devices.

Hammond Manufacturing was founded in 1917 in Guelph, Ontario, Canada. In the early years, the Company manufactured radios, power amplifiers and battery eliminators. During the late 1920's Hammond focused its efforts on the manufacturing of transformers for the broadcast and communications industries. The explosive demand for electrical products of all kinds during the 1950's and 1960's created many opportunities for new products and diversification. During these years Hammond became a leading supplier of transformers and enclosures for the electrical and electronic industries.

Each denial increases your costs and jeopardizes your revenue. How much are you spending to get paid? Download this infographic from Change Healthcare to uncover the real cost of denials.
Denials represent a clear and present financial danger for physician practices. Not only do they have the potential to seriously reduce collections and undermine cash flow, they also are time consuming and costly to resolve. Revenue Performance Advisor helps providers minimize the likelihood of denials occurring in the first place. And when they do, you'll be able to resolve them quickly and efficiently.
Is your practice struggling to collect payments from patients? You aren't alone. High-deductible plans are a game changer. According to JAMA, the percentage of provider revenue coming from patients is expected to increase by 50% in the next three years. Check out this eBook to learn about strategies and technologies than can help you navigate this new reality.
There are 3 types of search. Please only use one option at a time.
1) Build a boolean search string.
Ensure that document matches include...
2) Search for a phrase:
3) Search on part of a word:
Information on how to use Search
There are 2 types of basic queries: Terms and Phrases.
A Term is a single word search.
A Phrase would wrap a string of words in quotes and find matches on the extact string.
Boolean Operators You can combine basic queries with Boolean operators to form a more complex query. Boolean operators define the relationships between Terms or Phrases. Our search supports the following Boolean operators: AND, "+", OR, NOT and "-". Please note that Boolean operators must be all uppercase.
AND example search: default AND document
This is the default operator. It will be used if there is no Boolean operator between two terms. For example:
default document is the same as default AND document. In this case both terms need to exist within a listing to find a match on that listing.The + character is synonymous with using AND.
OR example search: default OR document
In this case just one of the terms needs to exist within a listing to find a match on that listing.
NOT example search: default NOT "document type"
The NOT operator excludes documents that contain the term (or phrase) after NOT. So a listing match would have to include the word default but not the phrase "document type". The - character is synonymous with using NOT.
Wildcard/Prefix queries You can perform "wildcard" or "prefix" queries using the '*' operator. Whereas all of the previous search found exact matches on the whole term or phrase, a wildcard search will find partial matches.
example search: ehr*
This query will match all documents containing words beginning with the prefix 'ehr' like the word Ehrlichia.
