Float current monitoring

Multitel’s FCCP

Multitel’s float current monitoring solution FCCP detects potential battery degradation before getting into a thermal runaway condition with a VRLA and UPS battery thermal runaway detector. The FCCP is also ideal for detection of open circuit between the battery and its charging element.

 

Multitel’s FCCP is a proactive way to detect VRLA and VLA battery issues before they impact end users’ quality of service.  Multitel’s patented technology enable a reliable, precise and consistent measure of float charging currents, even in noisy environment such as large UPS systems which provides elevated ripple currents.

 

Multitel’s FCCP innovative measuring technique uses a split core transducer to simplify installation and get accurate reading as low as 2 mA resolution.  A set of smart relay contact triggers remote alarms only when an abnormal high or low charging current is present, it is not impacted by the discharge and recharge current related to normal battery rundown.  Along with other critical battery parameters, the FCCP makes an ideal solution to provide SOC and SOH conditions of your batteries while providing conformity to certain regulation such as IFC, NERC’s PRC and TPL.

 

The FCCP can be integrated into any critical location where stationary batteries are found such as: DLCs, CEVs, WICS, Huts, Cellular sites, Customer premises and Electric Power Utility Substations.

Compliance

NERC PRC-005-6

NERC standards require a testing program for backup power systems, such as bulk power systems and batteries. Power utilities owners need to document and implement programs for the maintenance of all protection system.

Multitel’s FCCP solution for float current monitoring helps power utilities and asset owner to help comply with NERC PRC-005-6 data collection frequency and measurement criteria. It allows users to determine if the station battery can perform as manufactured by evaluating cell/unit measurements indicative of battery performance against the station battery baseline.

 

NERC TPL-001-5

NERC TPL-001-5 is a newly established standard that requires Power Utilities to address single points of failures on their protection systems. Non-redundant components of a protection system such as a “Station DC supply” with only one charger and one battery string is considered a single point of failure.

Based on “footnote 13c” of the standard, Power Utilities can exclude a non-redundant station DC supply if it is monitored 24/7 for low voltages and open circuits, as well as reporting to a control center.  Monitoring the float charging current is the best and most reliable method for verifying battery continuity as it proves that the battery charger is connected to the batteries, all intercell connections are satisfactory and batteries are fully charged.

IFC section 608 and NFPA 1. Article 52.

IFC and NFPA recommend that VRLA battery systems have approved method to preclude, detect and control thermal runaway. Multitel’s FCCP helps to meet this requirement by providing an effective measuring technique to get accurate readings of charging currents to detect signs of potential battery degradation and prevent thermal runaway long before damage begins.

FCCP questions

Yes. The FCCP provides a 0-50mV analog output signal directly proportional to the 0 to 5A input range. Therefore, using the Multitel FUSION RMU or the analog signal, you can precisely monitor and trend float current over time.

A thermal runaway is an incident that builds up slowly over time and results in an uncontrollable increase of temperature. Undetected thermal runaways can lead to costly damage to equipment and, in more severe case, fire or personal injury. Thermal runaway protection is therefore essential for your facility.

Yes. The FCCP will help you comply with IFC 608.3 and NFPA 1. Article 52 as a device to preclude, detect and control thermal runaway.
