Fault Circuit Indicator FLOCO, real time network monitoring. The right solution for fault location in medium-voltage networks, with fully integrated supervisory systems.
Single-Phase Recloser ROCKET-1, Single and three phase network protection and automation. A smart grid solution, remotely controlled and reducing up to 80% of permanent faults.



We provide a range of Entec power distribution and control solutions including load break switches, solid ring main units, solid insulated reclosers and feed protection relays.



The Eaton Cooper Power series provides a range of utility and grid solutions including utility fuses, lightning/surge arresters, voltage regulators, vacuum fault interrupter switchgear, pole-mounted capacitor bank and metal-enclosed, pad-mounted capacitor banks.




MacLean Power distribution transformers are built for New Zealand's toughest network conditions. Rated at 11kV : 230V : 1kVA, each unit features a 304 stainless steel tank and cover with a polyester powder coated finish, standard NEMA hanger bracket, and primary connection wildlife guards, all finished with stainless steel hardware.
Internally, the transformers use all-copper windings for low losses, an internal HV fuse, and high strength polymer LV bushings, backed by a pressure safety valve with manual release for added protection. They're well suited to reclosers, capacitor banks, automation switches, and other remote loads.

Experience the next level of automatic circuit protection. The PVR-27 delivers uncompromising performance with over-spec vacuum interrupters, proven SEL651R MRI compatibility, and a compact, eco-friendly design, ready to reduce outage times and simplify operations.



INERTIA Engineering & Machine Works Inc. manufacture specialised gang-operated air-break switches for regulator by-passing and distribution and transmission applications. INERTIA's signature products exceed the IEEE and IEC standards and are suitable for New Zealand's harshest environments where corrosive, salt spray, dust and other natural contaminants need to be considered by the asset owner.



The same trusted partnerships now extend to the systems that monitor, control and protect the network.
