Insulation Monitoring Device IMD for Industry applications

Product catalog summary

Overview: The document describes the IMD Insulation Monitoring Device, which measures insulation resistance using a dual-frequency sinusoidal voltage method. This technique is effective across various power supply systems, including DC and AC, and complies with IEC 61557-8 standards.

Operation Principle: The device continuously supplies two sinusoidal voltages to the insulated system, causing a current that flows through the insulation resistance and capacitance. The current's amplitude and phase angles are measured and analyzed to calculate resistance and capacitance values. The system automatically adjusts frequencies for optimal accuracy and response time, even in the presence of subharmonic noise.

Features: Key features include a Modbus/TCP interface for remote monitoring, automatic network impedance and capacitance recognition, load and temperature monitoring, and a removable microSD card for logging changes in capacitance and resistance. The device is suitable for frequency converter applications and can connect to PE conductor monitoring units.

Specifications: The device operates with a nominal input voltage of 110-240 VAC or 110-300 VDC, with a line frequency of 48-62 Hz. It measures resistance from 20kΩ to 10MΩ and capacitance from 100nF to 100uF. The system frequency ranges from DC to 500Hz, with a test voltage of 30Vp max. It includes three alarm contacts with settable limits and supports RS-485 serial connections.

Standards and Safety: The device complies with IEC 61557-8:2014 for measurements and various safety and EMC standards, including IEC 61010-1:2010+AMD1:2016 and IEC 61326-2-4. It is SGS Tüv SAAR type approved and tested by Nemko.

Physical Characteristics: The IM-01.IND model measures 160 x 110 x 62 mm and weighs 0.35 kg. It is made of plastic and can be mounted using a DIN rail clamp or screws.

Accessories: Available accessories include the CLT-01 current loop transmitter and high voltage couplers (HVC-16AC, HVC-40AC, HVC-72AC) for monitoring industrial isolated networks with voltages up to 7200VAC.

Company Information: Trafox, a brand of Muuntosähkö Oy, specializes in transformers, chokes, filters, and monitoring devices. The company is based in Helsinki, Finland, with additional locations in Suzhou, China, and Estonia.
