ELECTRICAL SAFETY
There are several compelling reasons to use an insulation monitoring system in critical environments
l The early detection of potential electric faults prevents risky situations during critical functions; for example during surgery.
l They allow more efficient and effective use of valuable surgical and production equipment:
l Predictable and timely maintenance results in smaller operating costs.
the personnel in the case of leakage currents (low insulation level) and breakage, loosening, or disconnection of a PE-wire. It uses light and sound to indicate the alarm to the relevant personnel. The M-7 isolation-transformer
monitoring panel is also placed in the handling room, this time to inform staff if it detects the overloading or overheating of the isolation transformer.
Operational reliability The pace of technology development means new types of electrical devices are regularly introduced to operating rooms, ATEX-premises, and other critical
l Reliable technology allows for improved planning of operations and better organisation of shift- patterns, giving an increase in productivity.
l The usable life of expensive surgical and production equipment is increased.
environments. To stay ahead of this evolution and in order to remain at the cutting edge, PPO-Elektroniikka Oy continuously carry out lengthy and advanced R&D projects, which have resulted in several generations of their monitoring systems. It is essential to continuously conduct state-of-the-art engineering and design
activity in order to ensure continued compatibility with the latest technologies, as well as previous-generation devices. Some of the modern features added
to the insulation monitoring solution include the measurement of transformer overloading and overheating, as well as DIN rail compatibility. The standardised DIN rail is widely
used in electronic devices and units such as switchboards and electrical cabinets. It enables the convenient installation of resettable fuses, contactors, residual- current devices, modular terminal blocks, and other components. New electrical equipment is regularly
being installed in operating rooms, ATEX-premises, and similar critical environments. Sometimes this results in issues between the previously installed and new equipment, which may cause disturbances in the power supply or in the electrical devices. If this occurs, to enable troubleshooting and diagnostics PPO-Elektroniikka Oy also consult the manufacturers or dealers of the new equipment. The company also actively partners
with distributors, providing them with training, and support in sales; installation and commissioning; testing; and the long-term maintenance of their equipment.
