OVERVIEW
This chapter describes the GLC-10000 in a nutshell, including the
main features, front and rear panel description, and the power up
sequence.
Introduction
Overview
Many electrical products must undergo electrical
safety testing to ensure their safety. These tests
include insulation resistance, withstand voltage,
ground continuity and leakage current tests. These
tests are complex and critical for safety standards
compliance.
To comply with international standards and to
ensure operator safety, leakage current tests are
also performed under normal and faulty operating
conditions.
Leakage current tests can be separated into 3 basic
types:
Earth Leakage current
Enclosure Leakage current
Patient Leakage current
The GLC-10000 complies with IEC, UL and other
international electrical safety standards requiring
leakage current measurement.

Measurement Principles
Background
Leakage current can be categorized into 3 types:
Electric current that flows through the body of
someone who touches the equipment, the current that
flows through a protective grounding wire to earth and
the current that flows through a human body
connected to an applied part. When testing the
leakage current of an EUT (equipment under test),
testing must be performed under normal and single
fault conditions.
As shown below, a number of relays are used to
simulate different fault conditions. Power to the EUT
is normally open and thus turning off the power
disconnects one wire on the power line.

OVERVIEW
15
Single Fault conditions include the following:
1. Earth disconnected (excluding earth leakage
current tests).
2. Disconnected neutral power line.
3. External equipment failure. (Patient leakage
current II, Patient Leakage Current III).
Polarity of the power supply can also be switched
to measure the leakage current under test. Thus
the polarity of the power supply should also be
taken into account.
Measurement
Methods
The diagram below shows how the probes, MD’s
and power supply are connected for different
leakage current tests.
Measuring Devices
Background
Leakage current (touch current) tests that measure
electrical equipment require a circuit network that can
simulate the impedance of a human body. The
impedance of a human body varies with the contact
points, area and the path of conduction. Thus the
circuit network used to simulate the impedance of a
human body varies with the type of test performed. As
such, the safety standards used to measure leakage
current also varies greatly. The circuit networks used
are known as measuring devices, or MD for short. MD
circuits are resistor-capacitor (RC) circuits. The GLC-
10000 supports 12 different measuring devices.

OVERVIEW

Note
When conducting leakage current tests, please note
the following:
1. Under normal operating conditions, leakage
current is measured when an electrical device
under test is properly insulated with earth. If
the device is not properly insulated, the
leakage current that is conducted through the
measurement network may be invalid.
2. Leakage current tests involve high voltages.
When working with high voltages, testing
personnel should use proper safety
precautions. All test labs should establish
safety rules to cut-off power to an EUT should
conditions become unsafe. Contacting any
electrical appliance under test is extremely
hazardous and should not be attempted.
3. The surrounding environment has an effect
upon leakage current tests. Avoid high
temperatures, high humidity and surface
pollutants on the enclosure surface as they can
all have an influence on the resulting data.
