Line Isolation Monitor Testing in Los Angeles California


Isolated power systems (IPS) are an essential component of electrical safety in healthcare facilities. They are designed to provide an isolated power supply to critical patient care areas, reducing the risk of electrical shock and electrocution. An important part of maintaining the safety and reliability of IPS is regular testing of the system's line isolation monitor (LIM). BiomedRx, a leading provider of medical equipment maintenance services in Los Angeles, offers comprehensive IPS testing and LIM testing services to healthcare facilities across the region.

In this article, we will discuss the importance of IPS and LIM testing in healthcare facilities, the relevant standards and regulations, and the specific services offered by BiomedRx in the Los Angeles area.

Importance of Isolated Power System and Line Isolation Monitor Testing

Isolated power systems (IPS) are designed to provide a reliable and isolated power supply to critical patient care areas, such as operating rooms and intensive care units. The IPS is a secondary power supply, separate from the building's primary electrical system, which reduces the risk of electrical shock and electrocution. The IPS is typically supplied through a special isolation transformer, which provides electrical isolation between the primary and secondary windings.

However, like any electrical system, IPS can fail due to a variety of factors, including equipment malfunction, improper installation, and environmental factors. Regular testing of the IPS is necessary to ensure that it is functioning properly and providing the necessary level of electrical isolation.

The line isolation monitor (LIM) is a critical component of the IPS. The LIM continuously monitors the electrical isolation between the secondary windings of the isolation transformer and ground. If the isolation resistance falls below a certain threshold, the LIM will activate an alarm and/or shut off the power to the secondary circuit. This ensures that if a fault occurs, the fault current is limited and cannot cause electrical shock or electrocution.

Testing of the LIM is essential to ensure that it is functioning properly and providing the necessary level of protection. Regular testing of the LIM can identify potential problems before they become a safety hazard, and can help to prevent costly downtime due to electrical faults.

Relevant Standards and Regulations

The National Fire Protection Association (NFPA) Standard 99 - Health Care Facilities Code, is the most comprehensive source of information on the design, installation, and maintenance of electrical systems in healthcare facilities. NFPA 99 provides specific guidelines for the design and installation of IPS, as well as the testing and maintenance requirements for these systems.

The Joint Commission is another important regulatory agency that provides standards and guidelines for healthcare facilities. The Joint Commission requires that healthcare facilities comply with all applicable codes and standards, including NFPA 99, in order to maintain accreditation.

    Lately there has been controversy in the hospital engineering community concerning the use of isolated power systems and the 2012 changes in the National Fire Protection Association standard, NFPA 99.

    Section 3.3.89 of NFPA99 2012 defines an Isolated Power System as "A system comprising an isolation transformer or its equivalent, a line isolation monitor, and its ungrounded circuit conductors."

    Section 3.3.9 of NFPA99 2012 defines a Line Isolation Monitor as "A test instrument designed to continually check the balanced and unbalanced impedance from each line of an isolated circuit to ground and equipped with a built-in test circuit to exercise the alarm without adding to the leakage current hazard." In an isolated power circuit, a ground fault would result in an alarm, but power would not be interrupted.

    Section 3.3.184 of NFPA99 2012 defines a Wet Procedure Location as "The area in a patient care room where a procedure is performed that is normally subject to wet conditions while patients are present, including standing fluids on the floor or drenching of the work area, either of which condition is intimate to the patient or staff."

    Section 6.3.2.2.1.2(C) of NFPA99 2012 addresses isolated power with regard to Critical Care Areas and states "Where used in locations such as critical care areas, isolated power panels shall be permitted in those locations."

    Section 6.3.2.2.8 of NFPA99 2012 addresses Wet Procedure Locations.

    Section 6.3.2.2.8.1 of NFPA99 2012 states "Wet procedure locations shall be provided with special protection against electric shock."

    Section 6.3.2.2.8.4 of NFPA99 2012 states "Operating rooms shall be considered to be a wet procedure location, unless a risk assessment conducted by the health care governing body determines otherwise.

    This is the most controversial section. A risk assessment by the health care governing body can in fact deem an operating room not to be a wet procedure location. This would be contingent on interpretation of the mopping of the floor which occurs between cases as "drenching", as defined in Section 3.3.89 above.

    Section 6.3.2.2.8.6 of NFPA99 2012 states "The use of an isolated power system (IPS) shall be permitted as a protective means capable of limiting ground-fault current without power interruption. When installed, such a power system shall conform to the requirements of 6.3.2.6."

    Section 6.3.2.2.8.7 of NFPA99 2012 states "Operating rooms defined as wet procedure locations shall be protected by either isolated power or ground fault circuit interrupters."

    Section 6.3.2.2.9 of NFPA99 2012 addresses Isolated Power

    Section 6.3.2.2.9.2 of NFPA99 2012 states "The system shall be permitted to be installed where it conforms to the performance requirements specified in 6.3.2.6.

    Section 6.3.2.6.2.2 of NFPA99 2012 addresses Line Isolation Monitors

    Section 6.3.2.6.3.2 of NFPA99 2012 states "The monitor shall be designed such that a green signal lamp, conspicuously visible in the area where the line isolation monitor is utilized, remains lighted when the system is adequately isolated from ground; and an adjacent red signal lamp and an audible warning signal (remote if desired) shall be energized when the total hazard current (consisting of possible resistive or capacitive leakage currents) from either isolated conductor to ground reaches a threshold value of 5.0 mA under normal line voltage conditions. The line isolation monitor shall not alarm for a fault hazard current of less than 3.7 mA.

    This is interesting, as many of the Line Isolation Monitors still in use are older, often analog units that are set to alarm at only 2 mA. These units must be replaced immediately, as it is a violation of code to use them.

    Section 6.3.3.3 of NFPA99 2012 addresses Performance Criteria and Testing for Isolated Power Systems.

    Section 6.3.3.3.2 of NFPA99 2012 Line Isolation Monitor Tests states "The line isolation monitor (LIM) circuit shall be tested after installation, and prior to being placed in service, by successively grounding each line of the energized distribution system through a resistor whose value is 200 x V (ohms), where V equals measured line voltage. The visual and alarms shall be activated."

    Section 6.3.4.1 of NFPA99 2012 addresses Maintenance and Testing of the Electrical System.

    Section 6.3.4.1.4 of NFPA99 2012 states "The LIM circuit shall be tested at intervals of not more than 1 month by actuating the LIM test switch. For a LIM circuit with automated self-test and self-calibration capabilities, this test shall be performed at intervals of not more than 12 months. Actuation of the test switch shall activate both visual and audible alarm indicators.

    Section 6.3.4.2 of NFPA99 2012 addresses Record Keeping.

    Section 6.3.4.2.1.1 of NFPA99 2012 states "A record shall be maintained of the tests required by this chapter and associated repairs or modification.

    Section 6.3.4.2.1.2 of NFPA99 2012 states "At a minimum, the record shall contain the date, the rooms or areas tested, and an indication of which items have met, or have failed to meet, the performance requirements of this chapter.

    Section 6.3.4..2.2 of NFPA99 2012 Isolated Power System (Where Installed) states "A permanent record shall be kept of the results of each of the tests.

    Here is another video about our isolated power system and line isolation monitor inspection services in accordance with NFPA 99.

    A complete inspection of all devices for polarity.

    Verification that all applicable sections of code requirements are being met.

    Confirmation that the impedance to ground of both conductors of the isolated system exceeds 200,000 ohms when installed. Document what corrective action that needs to be completed to meet that standard.

    Log voltage and millivolt readings for criteria for acceptability for new construction or existing rooms.

    Line isolation monitors will be tested and all readings will be taken to make sure that they not only are working but working within the specifications of the code requirements from when they were installed.

    Upon completion of testing, a technician shall meet with hospital medical and maintenance staff to explain the operation of isolated power systems; explain alarm procedures and answer any questions.

    Periodic testing and logging for future test required by NFPA 99 will be explained to maintenance staff.

    After all tests have been successfully completed, a written certification will show that all systems comply with codes, good installation practices and specifications. We will also provide written confirmation that the testing logbooks have been delivered to the hospital maintenance staff and that they are up to date.


    Training: "Administrative authorities should ascertain that electric maintenance personnel are completely familiar with the function and proper operation of ungrounded electric circuits." For liability and operation, has your hospital personnel, that are now maintaining your Isolated Power Systems, been trained by a proper instructor? Many hospitals had training when the equipment was first installed but after many years those individuals are no longer with the hospital. BiomedRx can train your current maintenance staff on any manufacturer's isolated power systems. NFPA 99 10.5.8.1.1 states "The Health Care Facilities shall provide programs of continuing education for its personnel.
