Megger BA-185 Current Transformer Burden Ammeter

Megger BA-185 Current Transformer Burden Ammeter

The Megger BA-185 current transformer burden ammeter is a rugged, portable instrument designed to field-test current-transformer (CT) installations. It helps locate short-circuited secondary turns, short-circuited primary turns, short-circuited secondary wiring, high-resistance connections in the secondary circuit and grounding problems in the secondary winding. Within the accuracy limits of the CT, a healthy current transformer shows no noticeable change in ratio when secondary burden is added; the BA-185 applies and measures that burden so faults become easy to identify. Switch-selected current ranges and a clear, easy-to-read analogue meter make it fast and practical to use in the field.

Key features of the Megger BA-185 burden ammeter

• Switch-selected ranges – 1.25, 2.5, 5 and 10 A AC ranges for a wide range of CT secondaries.
• Clear analogue meter – easy-to-read 2.5 in (64 mm) meter with uniformly spaced divisions and a rugged clear plastic cover.
• Comprehensive CT fault detection – finds shorted secondary/primary turns, shorted secondary wiring, high-resistance connections and grounding faults.
• Rugged and portable – compact, lightweight (1.1 kg) instrument built for field use.
• Simple burden testing – applies and measures secondary burden to verify CT performance.
