In this month’s article the testing capabilities of RHM International’s new High Voltage Test Laboratory are discussed in more detail. The main purpose of the lab is to provide routine testing for RHM International’s manufactured products (bushings, current transformers, cable terminations) with nominal voltages up to 500-600kV. The lab also can perform high-voltage insulation tests […]
RHM International is opening of a new North American Production and Test site in Hudson, NH
RHM International is ramping up its production readiness with a new North American site that included an 18 month construction installation project of a new high voltage testing laboratory (see blog for description of the endeavor).

Transformer Bushing Standards
In North America the three main bushing standards that are used are CAN CSA C88.1, IEEE C57.19.00/C57.19.01 and IEC60137. The CSA standard is in large part an adoption of the IEEE standard with some specific Canadian requirements (e.g. operational capability at -50°C is seen more as a standard requirement than a special requirement). However dimensional […]
Transformer Bushing Replacement – RHM International Supplies Like for Like Non-Standard Transformer Bushing Dimensions
Continuing with the topic of bushing replacements and the challenges of replacing vintage style oil-filled bushings with current standard bushings, the following is an example of how the RIF® dry type bushing technology could meet the non-standard dimensional requirements of a COTA bushing replacement. Replacement of a COTA 138 kV, 800 A, 650 kV BIL […]
Do You Have a Transformer Bushing Replacement Program?
Most utilities today are operating with an aging transformer fleet that although significant may still have 10 to 20 years of life expectancy. However with these aging assets comes the problem of component reliability. To ensure that the transformers can meet their projected life expectancies money has to be spent replacing or refurbishing key components […]
