Features and Specifications

LightHouse
Medium Voltage
Sensor (MV)
Tollgrade offers LightHouse®, the next generation
real-time distribution monitoring solution
providing utilities actionable intelligence and
visibility into their network.
Our flexible solution consists of highly accurate
and intelligent Medium Voltage (MV) sensors
deployed in the field, and powerful analytics
software distributed in the network. Tollgrade’s
Sensor Management System (SMS) analytics
software supports utilities in diagnosing network
events, and accurately tracks system condition
information.
LightHouse provides the visibility utilities
require for:
■ Real-Time Fault Detection and Location
■ Asset Management
■ Vegetation Management
■ Continuous Three-Phase Load Monitoring
and Balancing
■ Power Quality
■ Line Sag
LightHouse MV Sensor The LightHouse Medium Voltage (MV) sensors
are easy to install and offer multiple advantages.
The sensors clamp directly onto the overhead
conductors, are inductively powered, store
energy without a battery, and maintain
communication in the event of an outage.
Our accurate MV sensors support multiple smart-
grid applications and are software defined, so
utilities do not need to invest in point products for
specific applications. LightHouse gives utilities
the future-safe, agnostic solution they require.
LightHouse MV Features
Flexible Communications Backhaul
Our MV sensors support leading wireless
communications and automatically join the
backhaul network when activated. Our unique
agnostic approach allows us to integrate into the
existing utility infrastructure, or send information
directly back to our SMS software at the utility
head-end.
Low Current Operations
Our proprietary technology enables MV sensors
to operate at 6 amps, without the use of a battery.
Waveform Capture
LightHouse MV sensors capture waveforms
before, during and after events. Waveforms are
sent wirelessly in near real-time or stored for later
analysis.
Energy Storage without Battery
The LightHouse MV sensor is inductively
powered, and uses a super cap instead of a
maintenance prone battery to ensure cost
effective operations.
User Defined Thresholds and Parameters
Our solution is completely software-defined,
allowing users to customize their preferences by
setting their own thresholds and parameters for
events, rules, alarms and communications.
Key Measurements Include:
■ Nominal Current
■ Surge and Fault Current
■ Electric Field Strength
■ Wire Temperature
■ Harmonics

Dynamic Asset RatingHigh Level Comms Architecture
Hosted by
• Traditional 11kv Open Ring Topology
• Two of more routes from the primary substation to a ring of secondary substations
• This is an open ring with the open point being ideally at the null point
• Each secondary substation is connected to one supply route
• However each secondary substation has two potential sources of supply as closing the switch provides two routes back to the primary substation
• Automatic Load Transfer
• Dynamically alter the number of secondary substations that are fed from each supply route
• Closing the open switch and then remotely operating switches introduced between substations
• This allows load to be transferred from one supply route to another automatically
• PMUs used at assess the effect on the Grid
Hosted by
• Sectionalisers used to control the configuration of the Ring
• PMU being used to monitor both primary and secondary substations
• Load Transfer is automated using DMS. This may however have a element of manual intervention

Automatic Load TransferHigh Level Comms Architecture
Hosted by
• Similar to Automated Load Transfer
• Utilises the properties of the 11kV ring
• Each secondary substation on an open ring circuit has two potential sources of supply
• Rather than shifting load operationally between routes using switches, the meshed network is a passive solution in which a permanent closed ring is created giving a virtual null point.
• A set of “protection zones” need to be designed and implemented to ensure that the network can operate safely
• Power flow is improved as the mesh allows the current to choose the path of least resistance
Hosted by
• Close the open point, have a virtual null
• New graded protection using directional overcurrent
• Protection schemes choice driven by communications availability (WiMAX - 40ms!)
• Protection Scheme:
• Directional overcurrent with Blocking (200 ms requirement)
• Current differential (to test) (10ms requirement)
