A precise, automated, and standards-compliant solution for measuring surface insulation resistivity of electrical steel laminations

The FT300-N1 Franklin Tester is a high-precision testing instrument designed for accurate measurement of surface insulation resistivity in electrical steel laminations. Developed for laboratory testing, production quality control, and incoming material inspection. The FT300-N1 is ideal for evaluating CRGO, CRNO, motor laminations, transformer cores, and other electrical steel components.

Built in accordance with BIS 649, ASTM A717, and IEC 60404-11 standards, it delivers reliable, repeatable, and consistent test results for demanding industrial applications.

IEC 60404-11

BIS 649

ASTM A717

The FT300-N1 combines automated testing with a robust pneumatic mechanism to simplify the entire testing process. Equipped with an advanced test head featuring ten precision brass contacts and automatic carbide drilling, the instrument applies a stabilized DC test voltage while maintaining controlled pressure on the specimen. The measured current is processed automatically to calculate surface insulation resistivity, eliminating manual calculations and reducing operator dependence. This ensures fast, accurate, and repeatable measurements with minimal user intervention.

Automated Testing for Consistent Results

The FT300-N1 operates using an intelligent automated sequence that controls specimen clamping, drilling, pressure application, voltage stabilization, current measurement, and resistivity calculation. The pneumatic system can apply controlled pressure up to 900 PSI, ensuring uniform testing conditions across different specimen types. Test results for both sides of every lamination are automatically stored and displayed, allowing users to evaluate both individual surface resistivity and combined insulation performance with excellent repeatability.

Designed for Modern Laboratories and Production Facilities

Built for continuous industrial use, the FT300-N1 features a durable mechanical design, intuitive interface, and simple operation that minimizes operator training. Results can be saved directly to USB storage or printed using thermal or A4 printers, while integrated Wi-Fi connectivity provide convenient data management and reporting. Its combination of automation, precision, and compliance with international testing standards makes the FT300-N1 an ideal solution for manufacturers, testing laboratories, and quality assurance departments requiring dependable insulation resistivity testing of electrical steel laminations.

What is the FT300N1 Franklin Tester used for?

The FT300N1 measures the surface insulation resistivity between electrical steel laminations to evaluate the quality of insulation coating.

Good insulation between laminations minimizes eddy current losses, improves transformer and motor efficiency, and reduces core heating.

The FT300N1 performs testing according to BIS 649, ASTM A717, and IEC 60404-11 standards.

The instrument measures voltage, current, surface insulation resistivity (Rj), and combined insulation resistivity (Ri) for both sides of the specimen.

The FT300N1 uses ten precision brass contact electrodes along with carbide drills to ensure accurate insulation resistance measurement.

Yes. The FT300N1 stores measurements for Side A and Side B of each specimen and automatically calculates the combined insulation resistivity.

The instrument can store results for up to five laminations before clearing the measurement table.

Yes. Test results can be printed directly over USB or Wi-Fi or exported to a USB drive for documentation and record keeping.

The recommended specimen size is 115 mm × 280 mm, although other sizes within the specified range can also be tested.

Yes. The instrument uses a pneumatic system to apply controlled pressure during testing.

Instrument verification is performed using a copper plate. If the measured current exceeds 0.97 A, the instrument is considered to be operating correctly.
