New England High Voltage Testing Service

Testing is an essential process in the manufacturing and maintenance of high voltage equipment. It is far better to detect a component issue in a properly equipped laboratory than to subject yourself to an unknown risk that may result in costly down time when defective parts are in service. You can have peace of mind when your product passes our thorough tests.

RHM International's New England High Voltage Test Service Laboratory in Hudson, New Hampshire, is a new testing service option in the northeastern United States. We have qualified staff and calibrated equipment ready to meet your high voltage testing needs. We are committed to providing the best possible service and delivering high quality test results, tailored to your specific requirements.

Our High Voltage laboratory is completely shielded electromagnetically. The building is a six-sided Faraday cage with an integrated underground grid. A low resistance ground path coupled with dedicated isolation transformers and power filters ensures a background partial discharge well under 1 pC, allowing for very high precision measurements.

Approximately 8500 ft² of test space equipped with a 5T overhead bridge crane and state of the art test equipment allows the laboratory to provide high precision test services in accordance with IEEE, IEC and CSA standards, including any individual customer specified needs.
