PRODUCT FAMILY
The new products are additions to the S1 family of insulation testers. Structured as
follows:
S1-552
S1-1052
S1-554
S1-1054
5kV, 5mA Diagnostic insulation tester with 2mA noise rejection
10kV, 5mA Diagnostic insulation tester with 2mA noise rejection
5kV, 5mA Diagnostic insulation tester with 4mA noise rejection
10kV, 5mA Diagnostic insulation tester with 4mA noise rejection
Where does the name come from?
S1 is derived from “Series 1”. The Series 1 instruments were for many years
considered “the definitive insulation tester” in the market place and well known for
their heavy-duty output and reliability. Hence we have used S1 prefix for the heavyduty versions.

THIS PRODUCT IS USED FOR?
This product is used for diagnostic insulation testing with DC voltage, with the
additional benefit of being suitable for electrically noisy environments such as high
voltage switchyards. The aim is for the customer to be able to analyse the quality of
insulation within equipment such as line and substation transformers, circuit
breakers, switch panels, large motor/generator windings and HV cables etc. The high
5mA test current makes this product particularly suitable for testing high capacitive
loads such as long cables.
WHY?
Insulation is then monitored so that developing faults can be diagnosed and
corrective action taken before expensive failures occur. As part of maintenance
program diagnostic insulation testing can quite literally save many thousands times
the cost of the tester and labour in prevented breakdown costs.
However electrical interference experienced in many high voltage areas can result in
poor, unreliable or unstable readings making effective diagnostic testing of the
insulation impossible. In noisy 400kV plus switchyards interference currents up to
4mA are not uncommon. Currently only one competitor product quotes noise
rejection, and they claim 2mA rejection. The S1-554 and S1-1054 provides the
solution with a full 4mA of rejection.
The 10kV option (S1-1054) is suitable to test to IEEE standards for testing motors
rated greater than 12kV, with the additional benefit of future proofing the instrument
against advances in insulation technology.

TECHNICAL OVERVIEW
In summary the new instruments are identical to the existing S1-552 and S1-1052,
but better in one key respect. Noise rejection. Both the MIT and existing S1-XX52
range can reject 2mA of interference current. The new instruments can reject 4mA .
What is Interference (noise)?
Interference is the electrical noise produced due to a variety of frequencies, which
can appear on the sample being tested. It is usually due to induced currents or
voltages from adjacent equipment and is very common in substations, particularly
high voltage substations where power frequencies predominate. This electrical noise
superimposes an AC signal on the DC test current and can cause considerable
variations in readings and may prevent the operator getting a reading at all if it is
beyond the capabilities of the instrument.
In high noise environments high interference currents, can render most insulation
testers useless.
In short when selecting an insulation tester the customer must be aware of its
capability to cancel out the effects of this AC noise and its suitability for the testing
environment. Further more not all noise is limited to power frequencies, hence our
advanced instruments utilise software filters to eliminate the effects of this noise.

The solution?
The NEW S1-554 (5kV) and S1-1054 (10kV) are the latest heavy-duty insulation
testers from Megger with 5mA test current. However these instruments incorporate
the very latest in noise rejection technology to eliminate unwanted effects in these
high noise environments.
How is it used?
The instruments are equipped with the latest technology in both hardware and
firmware filtering. The default setting of the instrument is with the hardware filter
switched on and the firmware filter switched off.
The hardware filter removes faster variations due to the effects of noise and may be
switched off if desired to slightly speed up testing in quiet locations and when testing
high capacitance loads. This simply removes the impedance of the filter circuit.
The firmware filter averages out slow variations due to the effects of noise. The time
constant of the filtering is user selectable to 10, 30 or 100 seconds to suite. This can
be adjusted during the test to give the best result.
