HIGH VOLTAGE SAFETY

It is essential to follow safe working procedures when working with high voltage. Information

on accepted codes of practice should be obtained from your local heath and safety regulatory

body.

IEEE standard 510-1983 (IEEE Recommended Practices for Safety in High-Voltage and High-

Power Testing) provides a working framework for establishing safe procedures, but must be

read in conjunction with local regulations and accepted codes of practice.

The following excerpts are taken from IEEE 510

•All ungrounded terminals of the test equipment or apparatus under test should be

considered as energised.

•Common ground connections should be solidly connected to both the test set and the test

specimen. As a minimum, the current capacity of the ground leads should exceed that

necessary to carry the maximum possible ground current. The effect of ground potential

rise due to the resistance and reactance of the earth connection should be considered.

•Precautions should be taken to prevent accidental contact of live terminals by personnel,

either by shielding the live terminals or by providing barriers around the area.

•The circuit should include instrumentation for indicating the test voltages.

•Appropriate switching and, where appropriate, an observer should be provided for the

immediate de-energisation of test circuits for safety purposes. In the case of dc tests,

provisions for discharging and grounding charged terminals and supporting insulation

should also be included.

•High-voltage and high-power tests should be performed and supervised by qualified

personnel.

•Consideration should be given to safety regulations which may apply to specific

circumstances; for example, HSE, company, or government regulations.

In the use of signal-gathering equipment, each device should be used in such a manner that it

will not present a personnel hazard should it inadvertently become a part of the high-voltage

circuit, or fail to function properly.

1.1 Electrical Specification

1.1.1 Supply Requirements

KV5-100 mk2 115/230V ±10% 600VA max

KV3-250 mk2 115/230V ±10% 900VA max

1.1.2 Output Specifications

The output voltage, current and duty cycle are as follows:

Unit Output voltage

Output current

5 min on/

15 min off 1 min on/

15 min off 40 seconds on/

15 min off

KV5-100 mk2 0-5kV 100mA - -

KV4-300 mk2 0-4kV 200mA 300mA -

KV5-200 mk2 0-5kV 100mA 200mA -

KV6-80 0-6kV 80mA - -

One side of the high voltage transformer output is connected to the earth system of the

equipment.

1.1.3 Zero Voltage Interlock

The equipment is fitted with a zero volt interlock system on the output control. This interlock

prevents the output being energised unless the output control is in the minimum output

position.

1.1.4 External Interlock

The equipment is fitted with a external interlock system. The interlock socket on the back

panel must have a short circuit across it terminals to enable the output to be energised.

Note: the open circuit voltage across the interlock terminals is 240Vac and is connected

directly to the mains supply.

The unit is supplied with a plug fitted to the external interlock socket on the rear of the unit.

The plug contains a shorting link to enable the unit. If external interlocks are used, the

interlocks should replace the shorting link. Please note that the output will not switch on

without either the link fitted in the plug or a closed external interlock circuit.

1.2 Output Voltage Control

The output from the equipment is controlled from zero by means of the output control. To

increase the output voltage turn the control knob in a clockwise direction.

Note: The output cannot be energised unless the regulator knob is set to zero, thus operating the

zero voltage interlock switch.

1.3 Overload Protection

The equipment is fitted with a fuse and variable overload protection circuits as standard.

1.3.1 Variable overload

The variable overload protection system senses current changes in the high voltage circuit.

The trip levels are adjustable in two ranges each of 6 steps giving 2-12% and 20-120% rated

current.

KV6-80 1, 2, 4, 6, 8, 10mA 10, 20, 40, 60, 80, 100mA

The range change and selector switches are located on the front panel of the instrument.

The circuit will activate when the load current exceeds that set by the trip level selector switch.

WARNING

The variable overload trip circuit does not limit the output current.

1.4 Metering

The equipment is provided with the following metering ranges using analogue moving coil

meters:
