UNSPSC 39121033: Potential transformer

A potential transformer (PT) is a type of instrument transformer designed to provide a voltage in its secondary winding proportional to the voltage in its primary. They are commonly used in metering and protective relaying in the electrical power industry where they facilitate the safe measurement of voltages

UNSPSC 39121033 Potential transformer is a Commodity code describing specialized high-voltage testing and measurement modules, power distribution transformers (both pad-mounted and pole-mounted), substation power transformers, and associated electrical distribution components. State and local governments buy these products across utility operations, electric power production facilities, water treatment infrastructure, and emergency power systems. Recent solicitations show utility authorities, municipal electric departments, and special-purpose water and power agencies—including Kissimmee Utility Authority, Austin Energy, Florida Keys Electric Cooperative, and municipal utilities in Georgia, Florida, Connecticut, Texas, and Virginia—acquiring transformers and related equipment through IFB, RFQ, and RFP processes. The mix spans small single-unit purchases (one testing module, five pad-mount transformers) to system-wide procurement programs (14 reclosers with 35 overhead transformers, 12 to 15 pad-mount units, capacitor banks, and associated controls for grid maintenance and expansion).

Geographic activity clusters in Florida, Georgia, and Texas, with notable recent opportunities posted from Kissimmee, Florida Keys, Austin, Lubbock, and Monroe; secondary activity appears in Connecticut, Virginia, and other states. Representative recent opportunities include Kissimmee Utility Authority's sole-source notice (October 2026) for one Omicron CP TD12 high-voltage testing device with 12 kV output and 300 mA current capability; Florida Keys Electric Cooperative's quote request (October 2026) for 14 ABB-Elastimold 27 kV reclosers and 35 single-phase 1 kVA overhead transformers for 2027 system-wide installation, with evaluation weighted to cost (50%), manufacturing quality (25%), and material availability (25%); Austin Energy's IFB (October 2026) for capacitor banks and associated parts on an as-needed basis under a 24-month term with local and small business preferences of up to 5%; and the City of Covington, Georgia's IFB (October 2026) for five pad-mount transformers ranging from 750 to 2,000 kVA at specified voltage configurations. The code shows consistent demand for equipment meeting tight technical specifications, BABA compliance where applicable, and delivery within 30 to 90 days.
