Reliable Stray-Voltage Mitigation

Neutral Isolator

Product Description

Since 1983, Dairyland has offered the Neutral Isolator as the preferred solution for addressing “stray voltage” on farms. Power utilities who wish to isolate their primary neutral from the customer’s secondary neutral can prevent undesirable primary neutral-to-earth voltage (NEV) from affecting the customer system. Where utilities have concerns about NEV effects on dairy or other livestock operations, the Neutral Isolator offers the most effective and safe solution for separating the two systems under normal conditions, yet solidly re-bonding the two ground grids under lightning or AC fault conditions.

Note: The Dairyland model VTNI is not authorized for use in solving nuisance shock to persons at swimming pools or similar human health situations where structure to ground voltage is present.
