Product Description
The KV50-200 and KV100-100 are
high power, high voltage ac test systems designed for insulation
testing. These systems are equally suited to both development and
routine testing of electrical insulation systems and plant. Each
unit is available in either a low partial discharge version or
without a specified discharge level.
The equipment consists of
a control unit and a separate oil filled high voltage transformer,
linked by 5 metre supply and control cables. The control unit is
fitted with a comprehensive range of facilities for control,
metering and protection. Both systems include secondary tap
metering as standard to ensure accurate voltage metering. The
output voltage and current are displayed on large, linear analogue
instruments, and a variable electronic trip is provided, allowing
the trip current to be set to 10-110% of rated output.
The high voltage
transformer is housed in an oil-filled steel tank fitted with
swivel castors for mobility. The units use a low-discharge
oil-filled bushing for the HV output. Both the KV50-200 and
KV100-100 are equally suited to testing capacitive, resistive or
inductive test objects.
Low discharge versions of
the units are available as an option (KV50-200LD and KV100-100LD),
with maximum discharge levels of 1pC and 3pC respectively. The
partial discharge levels on the standard KV50-200 and KV100-100
are not specified. KV50-200 and KV100-100
Specification
Output
The output of the KV series units is by an oil filled high voltage
bushing. The earthy end of the HV winding is connected to earth
via the current metering circuit and a removable link. The
removable link allows equipment supplied by the user to be
connected into the earthy end of the HV winding for Tan-d
measurements.
