5-kV and 10-kV dc Insulation Resistance Testers

DESCRIPTION

The new range of insulation resistance testers consists of

three models: two 5 kV units (MIT515 and MIT525) and a

10 kV unit (MIT1025). Resistance measurement is available

up to 10 TΩ for the 5 kV models and 20 TΩ for the 10 kV

model. The new instruments are smaller and lighter than

previous models yet offer advanced features and rapid

charge capability.

A key productivity feature is the ability to take

measurements when connected to line power/mains with

a dead battery. Intelligent battery charging ensures the

optimum charge rate as a function of battery level, resulting

in minimum charge times.

The rugged, unique dual case design provides the ultimate

protection for a portable instrument and a clip-on lead

pouch ensures that leads remain with the instrument at

all times. The case lid is removable for improved terminal

access. IP rating is IP65 with the case closed preventing

water/dust ingress. High reliability and safety are built in;

all models are safety rated to CATIV 600 V and are double

insulated.

Five preset voltage ranges are provided in insulation

test mode, plus a user settable lock voltage range. Any

selectable test voltage may be locked and restored

via the selector switch, thereby increasing efficiency

of commissioning and repetitive tests. Preconfigured

diagnostic tests include Polarization Index (PI), Dielectric

Absorption Ratio (DAR), dielectric discharge (DD), Step

Voltage (SV) and ramp test.

The ramp function gradually increases voltage up to a

selected level while graphing current vs. voltage (graph

downloadable). Graphs can be compared to example

curves in IEEE 95-2002 to reveal a variety of faults difficult

to detect otherwise. Small defects can be easily detected

without risking the sudden large voltage increments

produced by a Step Voltage test. Monitoring the developing

graph during test enables the operator to terminate prior

to breakdown, thereby reducing the possibility of damage

to already flawed insulation. These units are particularly

informative on polyester, asphalt and epoxy-mica

insulations. They can also test voltage suppression devices.

Simplicity of operation is achieved with two rotary switches

and the large backlit display enables multiple results to be

displayed simultaneously.

Advanced memory storage includes time/date stamping of

results, logging of data and recall of results to screen. A

fully isolated USB device interface (type B) is used for safe

transfer of data to Megger’s PowerDB asset management

software.
