About The Position

The High Voltage (HV) Technician supports Accelerated Mobile Power's (AMP) field power generation operations at mission critical data center sites. This role is responsible for the safe operation, inspection, testing, troubleshooting, maintenance, commissioning support, and switching of medium voltage electrical systems associated with AMP owned generation assets and large power transformers. AMP's initial transformer configuration includes an outdoor oil filled 36/48/60 MVA power transformer with a 13.8 kV delta primary, 34.5 kV grounded wye secondary, copper windings, and an on load tap changer (OLTC). The role also supports associated 15 kV and 35 kV class switchgear, breakers, protective relays, grounding systems, cables, and balance of plant equipment. Future AMP sites may use different transformer ratings or system voltages, so qualification remains task, equipment, and voltage specific.
