00:09In an industry that requires accuracy and dependability.

00:12The selection of the finest quality raw materials is essential.

00:17Our fully integrated manufacturing process ensures quality control.

00:22From beginning to end the core of a merrimack current transformer is made of the highest

00:28quality grain oriented electrical grade silicon steel that has been manufactured in the US.

00:33To Merrimack's exacting standards for the secondary winding.

00:37We use premium electrolytic refined electrical grade insulated copper magnet wire.

00:43The annealing process is performed in our custom built ovens designed by MEMC

00:49specifically for annealing instrument transformer.

00:52Cor the annealing process is critical to ensure the core will deliver optimum accuracy and

00:58minimum excitation loss throughout the process. Fully automated oven controllers provide real

01:04time monitoring of temperature atmosphere and cycle time.

01:09The edge bonding and core insulation process prevents moisture ingress and protects against

01:15ambient humidity penetration in even the most demanding applications.

01:20A two part epoxy edge seal is applied and all core surfaces are covered with a high density

01:25insulation material.

01:27The secondary magnet wire winding is performed on automated winding machines that ensure the

01:32windings are equally distributed around the core to provide a low leakage reactance design.

01:38The encapsulation process uses a state of the art urethane casting system to provide a rugged

01:43exterior finish that will perform well in harsh environments.

01:47Our attention to detail and quality assurance can be seen at each stage of production where

01:53operators constantly monitor the process, measure performance and verify and document

02:00results.
