Ensuring continuity of service
in the event of an insulation fault
Continuity of service in an essential operational requirement for power networks.
The installation must also comply with specific rules to protect people and property.
These safety requirements involve the use of protective devices which
operate when there is a risk that could cause the network to become
partially unavailable.
The consequences can be significant:
> Total or partial stopping of the process.
> Partial or total loss of production.
An IT ("isolated from earth") earthing system is the only one in which
safety is assured without the need for additional protective equipment.
The installation can operate without endangering people even in the
presence of an initial insulation fault.
What do the standards say?
The IT earthing system is described in
several standards:
> IEC 60364-4-41
These standards clearly state that, with
the IT earthing system, the installation
must be isolated from earth or connected
to earth through a sufficiently high
impedance.
> IEC 60364-7-10
In the event of only one ground or earth
fault, the fault current is very low and
interruption is unnecessary.
> IEC 61557-8
Insulation monitoring devices for IT earthing
systems.
Since a second fault would cause a circuit
breaker to trip, an insulation monitoring
device (IMD) is required to indicate an initial
fault.
> IEC 61557-9
This device must activate an audible and/or
visual signal.
Electrical installation in buildings:
- protection for safety,
- protection against electric shock.
Requirements for special installations
or locations - Medical locations.

The IT earthing system
The neutral of the transformer's secondary is not connected to earth,
and the load casing is connected to earth.
In the event of an insulation fault, current
cannot loop via the transformer's neutral:

> No dangerous contact voltage

> Very low fault currents.
Frame
Therefore, an IT earthing system guarantees
the best continuity of service.
However, the faulty circuit must be detected
and repaired before a second fault occurs
because a second fault would cause a short
circuit between phases and trigger protective
devices.
The installation can operate without
endangering people and equipment even
in the presence of an insulation fault.
As a result, protective devices are not
triggered.

Insulation monitoring devices
An indispensible solution for implementing an IT earthing network.
Insulation monitoring device (IMD):
These devices are mandatory in
an IT earthing system.
An insulation monitoring device injects DC or
low-frequency AC voltage between the network
and earth. The resulting current that flows
through the IMD is then measured.
The insulation value is calculated from this
low-frequency current.
Depending on the device, it can also be used
to:
> Display the insulation resistance value locally.
> Display the leakage capacitance value for
the monitored network.
> Store time-stamped alarms.
> Communicate with a supervisor.
Note: in an IT earthing system, a 50 Hz fault current is difficult
to measure since it loops through the capacitances distributed in
the network. The injected current will go through the insulation
monitor.
The IMD indicates the fault locally on its front
panel depending on the adjustable threshold set
on the device. It also activates a relay output
to a visual or audible indicator.
CPI

PE
Fault location:
On networks with many circuits, the IMD can be associated with a locator (XD301 – XD312) that can
identify the faulty circuit.
Such locators use the 2.5 Hz signal injected by the IMD to determine through which circuit the fault
current is flowing. There is no link between the locators and the IMD.

Advanced monitoring and fault location
This architecture is simple to implement since
there are no connections between the various
modules.The IMD (IM400) injects a 2.5 Hz
current and measures R and C using this current.
When the IM400 indicates a fault,
the maintenance team must locate
and clear the fault.
On a continuous process, this fault tracing
operation cannot be done by tripping circuit
breakers.
The XD312 modules measure the 2.5 Hz current
in each circuit and compare it with a threshold
value. The fault can then be located without
interference on the network.

Advantage of the
Schneider Electric offer
Measurement and display of C
Monitoring of C is essential on large networks since the C‑related
impedance can cause these networks to drift towards a TT arrangement,
which would give rise to a dangerous contact voltage and a high fault
current after an insulation fault. Only Schneider Electric displays
the C value.

Fault location without connection

This feature can simplify the implementation
and use of the system. It also removes any
limit on the number of XD312 locators.

and/or several buildings
Improvement
of preventive maintenance
Easy to manage IT islands are ideal for large
networks. If this is not possible, then it is
beneficial to have R and C measurements
per building or per critical circuit.
Per-feeder measurements enable constant
monitoring of the insulation change for each
group of critical circuits.
This feature,
which is exclusive to
Schneider Electric,
can meet the following
needs.
This gives the maintenance team a better
overview of the entire network and the
capability to anticipate issues.

The XLI300 provides both a communication
interface and IMD exclusion when the second
circuit breaker is closed (1).
This solution can also be combined with fault
location by an XD product, thereby enabling fault
location lower down in the network tree.
(1) Exclusion
The IMD injects a low frequency into the network. In a network with several incoming feeders, depending on the circuit breaker
position, there must be no more than one IMD injecting into the network. This injection exclusion is managed by the XLI300 interface.
At least one IMD, but no more than one, per subnetwork.

Fault locating

Manual fault locating
Once detected, an insulation fault must be
located and eliminated in order to guarantee
maximum continuity of supply.
XGR
Manual fault locating
The fault is located by testing different points
in the installation, one after another, using
a Vigilohm System XRM mobile receiver
and a current probe. The receiver captures
the low-frequency fault locating signal.
Two cases may be encountered:
> the installation is equipped with an IM400
or an XM300C. In this case, the manual
system is used to fine-tune the results
of the automatic locating system.
> the installation (relatively small or a sub-

Automatic fault locating
For easy locating of insulation faults, the
Vigilohm System makes it possible to
combine the IM400 and XM300C insulation
monitoring devices with:
> XD301/XD312 fault detectors to monitor
the different circuits of the installation.
> XRM receivers for mobile fault locating.
Fault locating in hospitals
The safety of the patient and operating
room staff is critical and standards prohibit
measurement currents greater than 1 mA.
This is not compatible with automatic fault
locating or the XGR portable generator.
However, the need to have automatic fault
locating is limited for two reasons:
> an insulation fault is rare in such a limited
area. It is not not so urgent to localize the
fault as the probability of having a second
fault is close to zero.
> it is easy to locate the fault by disconnecting
equipment or sequentially opening the circuit
breakers after using the room.

In this case, it is recommended to use the IT system for this

insulation faults can be determined before starting motors

The photovoltaic power system
Photovoltaic is a unique application which introduces the following specifications:
Selecting the IT Power System
In industry, the IT power system is used when availability is required. It’s the only grounding scheme that provides people
safety on first insulation fault without having to operate the protection devices and interrupting the power system.
It also allows limiting the faulty current on insulation fault in area that shows fire or explosion risks.
Insulation Monitoring Devices such as Vigilohm provide then an insulation alarm but do not trig the interruption of the power
system.
In photovoltaic applications, the IT power system allows limiting of the faulty current. People
safety against the risk of electric shock is provided by using class II DC power system (double isolation) in combination with
class II PV modules.
Within a grounded photovoltaic installation, an insulation fault may allow the circulation of an important faulty current with
risk of fire and/or destruction of material.
Using the IT power system (ungrounded power system) would allow limiting the faulty current on a first insulation fault thus
preventing any risk for the installation.
However it is then required to correct the insulation fault reported by the IMD as in case of a second insulation fault the
faulty current would be very important.
In some cases, upon detection of a first insulation fault the faulty part of the PV field and/or the inverter may be
disconnected; insulation fault correction is to be executed
Selecting the relevant Vigilohm device IM10 / IM20 / IM400
Selection is to be made mainly on the leakage capacitance linked to the size and peak power of the PV fields.
The IM400 is designed for the demanding applications including paralleled inverters.

The photovoltaic power system
Architectures
Several architectures can be found, hereafter some common ones:
Non isolated inverter
Isolated inverter
On installation with non isolated inverter, the IMD can be placed either on AC or on the DC side.
On installation with isolated inverter, the IMD must be placed on the DC side. Optionally an IMD can be placed on the AC side
(if in IT power system).
Non isolated inverter
Isolated inverter
In some installation, the insulation alarm output of the IMD can be used to disconnect the PV field from the inverter.
Increased value of C
Given the large surface area of PV modules constituting the photovoltaic field or the installation condition, it is possible to have
a value of the leakage capacitance (C) much higher than those usually witnessed in industry.
In industry, if the C value is very high, the impedance (Zc) linked to C could drive this network towards a TT network leading to
risk of dangerous contact voltage and high faulty current.
In photovoltaic applications like every DC applications, the high value of C has no consequences on people’s safety nor on the
faulty current.
Determining the C value
The value of the leakage capacitance of a photovoltaic system depends on several factors:
• Total capacity of the installation (related to the total surface area of the PV modules)
• PV modules technology
• Environmental conditions
• Installation topology (inverters in parallel or isolated by the primary transformer LV/MV)
• Day or night
• Age of the installation
• Capacity of the inverter
Measurements taken on numerous sites shows that the capacity does not exceed 2 μF/100 Kw under favourable conditions (in
the daytime) and do not exceed 20 μF / 100 Kw in less favourable conditions (dawn, frost).
Increased values often occur regularly (a few seconds to a few minutes) during phases of low production.

bb when associated with a circuit breaker possessing
an MN or MX release or with a contactor, the IM9-OL
protects motors against insulation faults that may be
produced during operating shutdowns (e.g. due to
condensation), by initiating an alarm or startup
lock-out.
Operation
bb Injection of DC voltage.
Voltage is applied, with the motor de-energised,
between the stator and earth, thereby creating a
leakage current in the motor insulation resistances.
bb 2 pre-set thresholds:
vv 1 prealarm threshold, adjustable in 8 steps
from 0.5 to 10 MΩ
vv 1 motor no start threshold, adjustable in 8 steps
from 0.25 to 2 MΩ.
An electronic device measures insulation from the
leakage current created by the voltage injected and
activates the prealarm or prevents starting when
insulation drops below the corresponding threshold.
Installation and connection

electronics (speed drives, motor starters, inverters, Thyristors…) and DC
components.
The IM400 is compatible with the following applications:
bb Power Circuits.
bb Control Circuits.
bb Photovoltaic Systems.
bb Impedant IT systems (HRG).
Main functions
bb Measurement
vv insulation resistance.
vv earth leakage capacitance.

Configuration management
On installations with monitoring devices covering variable configurations, only one
device at once is allowed to inject a voltage between earth and the installation
downstream on the incoming circuit breaker. The system must therefore manage the
exclusion of other monitoring devices. This is handled by either:
vv External logic relays for simple configurations.
vv Programmable Logic Controller for complex configurations.
In both cases, the injection inhibition input of the IM400 will be used.
Communication
IM400 has a built in Modbus RS485 port, it is used for remote monitoring and control.

Additional functions with other devices
Locating faulty circuits obtained by using the XM300C with:
bb XL308 and XL316 locators connected to 8 or 16 toroids; they are linked to the
XM300C by the Vigilohm System bus.
bb XD308C communicating detectors; they are linked to the XM300C by the Vigilohm
System bus and connected to the toroids on the circuits being monitored.
bb XD301 and XD312 detectors connected to toroids on the circuits being monitored.
bb XRM mobile receiver and current probe to fine-tune automatic locating results.
All these devices can be combined on a given installation.
Distributed measurements
This function is provided by combining an XM300C (or an XML308/316) with XL308
or XL316 locators. These locators measure insulation resistance and earth leakage
capacitance of each circuit. They have a fault alarm threshold that can be set to
different levels for each channel.

Configuration management
On installations with monitoring devices covering variable configurations, only
one device at once is allowed to inject a voltage between earth and the installation
downstream on the incoming circuit breaker. The system must therefore manage the
exclusion of other monitoring devices and each locator must identify the monitoring
device it is capturing the signal from. This is handled by either:
bb by the XTU300 interface for multiple busbar installations
bb by the XLI300 inrterface for single busbar installations.
In both cases, the circuit breaker position indication contacts are wired to the digital
inputs of the XM300C or the XML308/316. If only XD308C detectors are associated
with the XM300C, monitoring device exclusion is handle by the XLI300.

Configuration management
On installations with monitoring devices covering variable configurations, only
one device at once is allowed to inject a voltage between earth and the installation
downstream on the incoming circuit breaker. The system must manage the exclusion
of other monitoring devices and each locator must identify the monitoring device it is
capturing the signal from. This is handled by either:
bb the XTU300 interface for multiple busbar installations
bb the XLI300 inrterface for single busbar installations.
In both cases, the circuit breaker position indication contacts are wired to the digital
inputs of the XM300C or the XML308/316.

XRM mobile fault locating
Accessories
051350_SE_25
Receiver & current probes
Functions and characteristics
Operation
The XRM mobile receiver, used with a current probe, is mainly intended as an
enhancement to automatic fault locating systems.
It can be placed at various points along a faulty circuit, capturing the signal emitted
by an XM300C, XML308/316 or IM400 insulation monitoring device to determine
the exact location of the fault.
Three current probes are available, the XP15, XP50 and XP100. The set of live
conductors to be tested must have a maximum diameter of 12, 50 and 100 mm
respectively.
Display
The XRM receiver displays a number from 0 to 19, corresponding to the insulation
level:
bb 0: no fault
bb 19: solid fault (no insulation).

bb The XGR generator injects a 2.5 Hz AC voltage
between the installation and the earth, thereby creating
a leakage current which passes through the installation
insulation impedance.
bb The XRM mobile receiver is associated with one
of the three tong-type probes, XP15, XP50 or XP100,
and detects this leakage current at 2.5 Hz. It displays
a value between 1 and 19 according to the current
passing through the probe, thus detecting the leakage
current.
bb Three current probes are available, the XP15, XP50
and the XP100, for cables with diameters up to 12, 50
and 100 mm respectively. Older probe models are not
compatible with the XRM.

Use
The toroids are used to detect the earth leakage currents. They are used with the
Vigilohm System for the detection, locating and measurement of earth fault currents
on IT systems.
Closed toroids (type A) are suitable for new installations and extensions.
Split toroids (type OA) are suitable for renovated installations and extensions.
Functions
These toroids detect leakage current and transmit a proportional signal to the
associated receiver.
Closed toroids (type A).
042589_SE_46

(see table page 32)
Immunity to line overcurrents
Line overcurrents, due to motor starting or transformer energising, may result in
unnecessary fault detection by the detector.
A number of simple precautions can help prevent this from happening: when used
together they are even more effective:
bb place the toroid on a straight part of the cable
bb carefully centre the cable in the toroid
bb use a toroid with a diameter far larger than the diameter of the cable (2 x diameter)
(figure 1).
Figure 1.
Figure 2.
For severe operating conditions, use of a mild steel sleeve placed around the cable,
in the toroid, considerably increases immunity.
Recommended characteristics
bb Mild steel foil, 1/10 mm thick, to be wound several times around the cable in the
toroid (at least 1 mm thick).
bb Internal diameter of toroid > 1.4 x external diameter of the cable bundle (figure 2).
bb Toroid-detector link:
vv resistance y 3 Ω
vv cross-sectional area of wires: 0.75 mm² to 1.5 mm².
bb Maximum length: 100 m (see the toroid user manual for details).

Cardew selection table
The selection depends on:
bb the operating voltage Un of the installation
bb the installation insulation level
bb the connection point (neutral-earth or phase-earth).
Connecting conductor size
bb Cable or bar with a size adapted to the transformer rating.
bb The connecting conductor should be considered to be a protective conductor (PE)
and the calculation of its crosssectional area must satisfy applicable installation
standards, considering that this part of the installation is protected by protective
devices located upstream of the MV/LV transformer.
bb According to standard IEC 364, the formula for the calculation of the of the size of
the PE conductor is: S = √I2t/k where S is the cross-sectional area of the PE
conductor in mm2, I is the fault current, t is the operating time of the protective device
and k is a coefficient that depends on the metal and insulation material used for the
conductor.
bb Recommendation: if insulation monitoring is provided using the Vigilohm
System, install a type A toroid on the Cardew earthing circuit in order to monitor
operation of the Cardew. The toroid can be connected to an XD301/312 detector or
an XL308/316 or XML308/316 locating device.
