Chapter 1 - Introduction
M2H - MCM
This M2H - MCM Instrument system from Doble incorporates the latest measurement technology
to evaluate the insulation quality and assess the condition of high voltage power apparatus. This
semi-automated measurement system is designed to meet the needs of both laboratory and field-
testing personnel.
A straightforward user interface and automated measurement circuit removes human interaction,
thereby ensuring faster and more accurate results. The user interface incorporates a sunlight view-
able VGA screen, embedded keyboard and communication connectors (USB and LAN) to inter-
face with a PC or peripheral devices. The software will perform all relevant measurements and
calculations and display the result in an easy-to-read format. Up to 200 results can be stored in a
file, and the built-in hard drive provides virtually unlimited data storage. Memory stick support
provides an easy mechanism to transfer results back to a PC.
The MCM offers unique features to accurately test and evaluate electrical apparatus. The ability
to automatically remove the influence of electrostatic interference from the measurements ensures
precise and repeatable results. The optional temperature humidity sensor automatically measures
and records the ambient conditions to assist in the interpretation of the test results.
Use with your M2H
The MCM can be used with your existing M2H Transformer unit, providing you with a semi-
automated test capability at a fraction of the cost of a new test set. The MCM is substituted for the
M2H Instrument without any modifications to the hardware. Simply plug the inter-case lead of
the M2H Transformer into the MCM and all the measurements and calculations are performed
automatically.The MCM now allows M2H users to discern between Inductive and Capacitive
excitation current tests.
Use with an External Voltage Source
The MCM can also be used with an external voltage source using the External Reference lead
instead of the intercase connector. Just connect this lead to a high voltage capacitor to provide a
voltage reference, and configure the MCM with the characteristics of the capacitor.

Chapter 3 - Safety
Safety cannot be overstressed when working with and around high voltage. Companies that work
with high voltage should and do have precise rules for working in and around the various types of
high-voltage apparatus and their associated lines and conductors. The purpose of these notes is to
re-emphasize some generally acknowledged rules to observe, and to outline some specific rules to
strictly adhere to when making tests with Doble power-factor test equipment.
Perform all Doble power-factor tests with the apparatus to be tested completely de-energized and
isolated from the power supply. In addition, properly ground the apparatus housing or tank. There
is no substitute for a visual check to ensure that the apparatus terminals are isolated from the
power supply. For example, check each pole of a three-phase disconnect switch individually
because there have been cases where one pole of a gang-operated disconnect failed to open with
the others. Strictly observe all company rules and procedures for tagging and isolating the appara-
tus.
It is possible for apparatus insulation to retain some charge after being switched out of service.
Also, since field testing usually involves work in the vicinity of energized lines and apparatus, it
is possible for relatively high voltages to be induced in supposedly de-energized apparatus; this is
particularly true when long lengths of bus are left connected to the de-energized apparatus.
Trapped charges and induced voltages may not, by themselves, be sufficient to cause serious
injury. Even relatively low energy charges are potentially hazardous in that an unexpected shock
may cause a person to jump or fall from the apparatus. THEREFORE, SAFETY GROUNDS
SHOULD BE APPLIED TO ALL APPARATUS TERMINAL BEFORE DOING ANY WORK
ON THEM, AND BEFORE CONNECTING AND DISCONNECTING THE DOBLE TEST
LEADS.
Locate the Doble test set where the operator will have an unobstructed view of the apparatus
under test and of the various personnel assisting in the tests. Place the equipment such that proper
clearance is maintained between the test set and apparatus. In particular, it should be recognized
that damaged or defective apparatus may possibly fail during test.
Before proceeding with a test, the operator should discuss with the assistants the general plan for
conducting the tests, voltages to be applied, precautions to be observed, and proper use of safety
devices.

MCM User Guide
3-2 72A-2529-01 Rev. A 11/05
Doble power-factor field tests are equipped with a ground-relay scheme which prevents the test
voltage from being applied until the following preliminary conditions have been established:
1. Apply a heavy-duty safety ground (station ground) to the GROUND receptacle of the test
set (this should be the first step in setting up the test set).
2. Ground the test set case through the 120-Volt U-Polarized ac supply cord.
3. Set the VOLTAGE control at the fully counterclockwise zero voltage stop (i.e., gradually
raise the test voltage from zero).
After the set is properly grounded, the remaining test leads and High-Voltage Test Cable are
plugged into their proper receptacle. DO NOT CONNECT TEST LEADS TO THE APPARATUS
TERMINALS UNLESS THE LEADS ARE ALREADY CONNECTED TO THE SET.
Doble power-factor test sets require two people to operate. The test engineers operating the instru-
ment have their own Operator’s Switch; in addition, an Extension Safety Switch is provided (both
switches are of the spring-release type for quick action). With either switch off, remove all volt-
age to the High-Voltage Test Cable. In the absence of a Safety Supervisor, the assistant responsi-
ble for attaching the High-Voltage to the specimen should operate the Extension Safety Switch,
and position themselves to observe all terminals of the apparatus under test.
If this is not possible, then rope off the out-of-sight terminals with caution labels appropriately
placed, and a post a person in the vicinity to ensure safety.
EACH TIME THE TEST EQUIPMENT IS SET UP, PRIOR TO MAKING THE FIRST TEST,
BOTH SAFETY-SWITCH OPERATORS SHOULD COOPERATIVELY VERIFY THE COR-
RECT OPERATION OF BOTH SWITCHES.
It is apparent that the operator of the Extension Safety Switch should not close the switch until all
personnel are safely in the clear (PERSONNEL SHOULD NOT BE PERMITTED ON THE
APPARATUS WHILE TESTS ARE IN PROGRESS). Also, if unauthorized personnel should
enter the area, or if some undesirable situation should occur, the Extension-Safety-Switch opera-
tor should release their switch immediately and then notify the test-set operator.
USE BOTH SAFETY SWITCHES AT ALL TIMES. NEVER SHORT-CIRCUIT THEM AND
DO NOT USE FIXED MECHANICAL LOCKING MEANS FOR DEPRESSING THE
SWITCH BUTTON. THE SWITCH BUTTON MUST BE MANUALLY OPERATED AT ALL
TIMES.

MCM User Guide
72A-2529-01 Rev. A 11/05 3-3
The High-Voltage Test Cable used with Doble power-factor test equipment is a double-shielded
cable in which the high-voltage is exposed only at the outboard pothead tip. Nevertheless, the
Doble Engineering Company recommends that the you DO NOT HANDLE the High-Voltage
Test Cable while it is energized. Suspend or tie off the Cable in such a manner as to avoid han-
dling it.
In order to prevent confusion, the test set operator and assistant(s) should follow a uniform system
of visual and oral signals For example, when the test connections are complete, the assistant
should be present and call out, “Ready.” The operator, before bringing up the test voltage, should
acknowledge the assistant’s signal and advise by calling out, “Coming On.” Upon completing the
test, the operator should call out, “All Clear.” To demonstrate further that the test is complete, it is
good practice for the test set operator to extend the Operator’s Switch at arm’s length, with the
button released, for all to see.
NOTE
Never attempt to disconnect the High-Voltage Test Cable or the
Low-Voltage Lead(s) from either the terminals of the specimen to
which they are connected at the outboard end or, from the recepta-
cle of the test set at the inboard end, until or unless the test set
VOLTAGE Control is set to ZERO, and the set Operator’s Switch
and Extension Safety Switch are both released.
After the tests are complete, remove all test leads from the equipment terminals and set them on
the ground before disconnecting from the set. The heavy-duty test-set ground is the last lead to be
removed from the set.
In summary, many accidents which occur around high-voltage apparatus and lines involve per-
sonnel who are familiar, and perhaps too familiar, with high-voltage equipment. Staying alert and
ever watchful requires constant training. The greatest hazard is the possibility of getting on a
“live” circuit; to avoid this requires constant vigilance. In addition to the obvious dangers, person-
nel should recognize subtle dangers as well. For example, during transformer excitation-current
tests, the “floating” terminals may have significant voltage induced in them due to transformer
action; thus, all terminals of an apparatus under test, unless grounded, should be considered “live”
while the test is in progress. In the case of a potential transformer (or any transformers which may
be interconnected), voltage can be back-fed through the secondaries to produce high voltage on
the primary, although the primary is seemingly isolated from the power supply. This re-empha-
sizes another rule to completely isolate all apparatus terminals you test.
