Olsun Medium Voltage [MV] Substation Transformers Installed at Biogas Facilities For Renewable Natural Gas

Two OLSUN MV Dry Type Substation Transformers were installed at different biogas facilities in the state of Colorado. The substation transformer steps down the electrical connection from the main line to provide the power for the operation of the processing equipment at the facility. The switch allows the operator to open and close the line and the circuit breaker provides protection to the load. These facilities produce renewable natural gas and reduce greenhouse gas emissions.
