HIGH VOLTAGE MULTIPLEXER SW2001 HIOKI

Revolutionizing Motor Testing with SW2001

In the rigorous world of motor manufacturing and quality assurance, efficiency, accuracy, and safety are not just ideals but absolute necessities for competitive production. The Hioki SW2001 Multiplexer emerges as a revolutionary solution designed to boost efficiency with one multiplexer handling six tests. This innovative device fundamentally streamlines the entire motor inspection process by allowing multiple instruments to be connected simultaneously for a comprehensive suite of critical tests: resistance, inductance, surge, hipot, insulation resistance, and partial discharge (AC PD and surge PD). This integrated approach drastically eliminates the need for frequent manual reconnections, a common bottleneck in traditional testing setups. Whether integrated into serial motor test lines (conventional setups) or advanced parallel motor test lines, the SW2001 significantly reduces downtime, enhances throughput, and elevates the reliability of testing procedures, thereby driving efficiency across the production floor.

Scalable Channels for Diverse Needs

The adaptability of the Hioki SW2001 is a cornerstone of its design, allowing users to select the number of channels based on your testing needs: offering configurations of 4, 8, 16, or 24 channels. This modularity ensures that the multiplexer can be precisely tailored to the scale of operation, whether it’s for smaller batches or high-volume production. Its capacity to connect multiple instruments for six different types of tests not only streamlines motor inspections but also facilitates the simultaneous testing of up to three three-phase motors. This is further enhanced by the inclusion of two built-in thermistor temperature sensors, providing crucial thermal data during testing without requiring additional external equipment. The SW2001’s inherent flexibility makes it an ideal choice for diverse motor types and production volumes, optimizing resource utilization and maximizing testing capacity.

Enhanced Reliability and Operational Lifespan

The Hioki SW2001 is meticulously engineered to enhance reliability with reduced production line stops, providing both superior test accuracy and highly reproducible results. At the core of its robust performance is a highly reliable multiplexing design with an extended operational lifespan. The SW2001 explicitly employs highly durable high-voltage reed relays, a critical component chosen to significantly reduce maintenance frequency and costly downtime. These specialized relays operate by generating a magnetic field through current flow in an adjacent excitation coil, which in turn switches the contacts securely sealed inside a glass tube. This unique operating mechanism enables safe switching in high-voltage circuits, supporting a remarkable maximum peak voltage of 8 kV. Furthermore, this design actively helps to reduce the impact of leakage current on measurements, ensuring cleaner and more accurate data acquisition, even in challenging electrical environments, thereby boosting overall testing confidence.

Precision Through Advanced Insulation Design

Beyond its robust relay technology, the Hioki SW2001 multiplexer leverages advanced insulation design to ensure more accurate measurements and heightened safety. This comprehensive approach includes optimizing the spatial insulation distance between relays, a critical factor in preventing unwanted arcing and ensuring signal integrity. The selection of appropriate insulation materials is meticulous, designed to withstand high voltages and minimize parasitic capacitance or leakage. Furthermore, the use of high-voltage printed circuit boards significantly enhances insulation between relays and grounding, creating a highly stable and safe measurement environment. This meticulous attention to insulation effectively minimizes the impact of external noise and ensures that the multiplexer itself does not introduce errors into the sensitive motor test measurements. This combined focus on durable components and superior insulation directly translates into unparalleled measurement performance and long-term operational stability.

Guaranteed Measurement Performance and Durability

The Hioki SW2001 offers explicitly guaranteed measurement performance and high durability, instilling confidence in its long-term reliability and precision. Its impact on accuracy for critical tests is meticulously specified: for insulation resistance measurement, accuracy is guaranteed at 2% (across a range of 1 M$\Omega$ to 1 G$\Omega$). This precision is vital for verifying the integrity of motor windings. Furthermore, the magnitude of effect on AC PD (Partial Discharge) measurement is kept to an exceptionally low 40 pC or less during a 3 kV application, ensuring that the multiplexer itself does not significantly interfere with sensitive PD detection—a key indicator of insulation health. Regarding durability, the SW2001 boasts an impressive maximum allowable impulse current of 100 A peak, demonstrating its robustness against transient electrical events. The main circuit relay service life is rated at 5 million or more cycles (reference value), highlighting its long operational lifespan and reducing maintenance frequency, though this specific cycle count is a reference and not a direct guarantee.

Reliable Switching Across Voltage Ranges

The Hioki SW2001 is engineered for reliable switching, facilitating safe and precise measurements across the diverse set of motor tests that demand a wide range of electrical specifications. Motors require tests ranging from high sensitivity for low voltages for accurate measurement of motor winding resistance and inductance tests, where even millivolt-level signals are crucial, to demanding high-voltage resistance tests. The multiplexer is designed to handle this spectrum, accommodating up to a maximum of 5 kV RMS for AC/DC hipot tests and a substantial maximum of 8 kV peak for surge tests. This broad voltage capability means a single SW2001 can seamlessly integrate into various stages of motor testing, eliminating the need for multiple specialized switching units. Its robust design ensures that switching between these vastly different voltage levels occurs reliably and safely, preserving the integrity of both the test setup and the motor under evaluation.

Protecting Low-Voltage Meters from Stored Energy

A critical safety feature of the Hioki SW2001 is its capability for preventing damage to low-voltage meters from stored energy. In high-voltage tests, particularly surge tests, significant energy can be stored within the measured motor winding. If this residual energy is not properly discharged before connecting a sensitive, low-voltage measuring instrument (like a resistance meter or inductance meter), it can severely damage or even destroy the meter. The SW2001 addresses this by incorporating a sophisticated protective discharge function. This function allows the multiplexer to ground the output-side main circuit, thereby enabling it to discharge any residual energy accumulated in the winding. This discharge occurs safely and effectively prior to closing the I/O relay’s main circuit to a low-voltage instrument. This proactive safety mechanism safeguards valuable test equipment, extends its lifespan, and ensures consistent, accurate measurements without risk of electrical overload or damage.
