AC30 Non-contact AC Voltage Tester

G.L McGavin have been manufacturing High and Low voltage testers since 1975. The new G.L McGavin Digital hand held Proximity Tester AC30 is designed for Electricians, Technicians and the Fire & Rescue departments. For electricians it can be used for picking up live wires behind walls, identifying live cables and tracing live cable runs. For the Fire and Rescue it is used for the safety of the rescue personnel in situations where live voltage can be present impeding rescue operations. Because it is a Digital device it can be programmed to suit any application.

AC30 operation

When the unit is activated using the ON switch the unit will self test automatically ensuring the unit is in working order. The Self Test button is located on the front face of the tester. This is a full function test of all components of the unit testing:

·         Audio indicator

·         Visual indicator

·         Transistor circuit verification

The self test button is recommended to be used at regular intervals during the working day. In the event the tester fails please refer to (Service and trouble shooting).

The Self Test feature is designed as an independent circuit, apart from the detection circuit. This Self Test circuit produces an AC signal that the detection circuit can pick up, as it would pick up an outside signal source. This allows confidence that the AC30 Non-contact AC Voltage Tester is working correctly.

Fire & Rescue Vehicle Accidents

In the event a vehicle is the cause of damage to a power pole or any emergency situations, the result may bring down the attached lines. These lines are active and the surrounding area can be energised. A HAZARD AREA must be established until electrical authorities disconnect power.

• When arriving at the incident, turn on the GLM MINI to the high sensitivity setting.
• Press and hold the self test button and an audible repeating tone will be heard indicating a healthy unit.
• Place thumb and hand as indicated on unit with arm outstretched as the position of your hand and body determines the sensitivity of the unit. In this position maximum sensitivity is achieved.
• Wave the unit from side to side in the direction of the incidence.
• If the RED indicator and alarm sounds a voltage is detected.
  Note: As unit may detect power lines above in order to determine the location of the voltage source place the unit on the low setting and move to detect if power line is on the ground or above. By placing your hand in the middle of the unit not covering the front test area label, sensitivity is decreased providing an accurate location of voltage source.
• When voltage is detected from fallen power lines, contact supply authority immediately and erect a hazard area around scene to protect service officers and the general public.
• On notification from supply authority that power has been isolated retest the area again placing the unit on high with thumb on bottom of unit and follow the previous steps.

Commercial & Residential Properties

On the arrival at a structure fire, identification of power lines and connection to property must be located and identified; procedures for active live power isolation and disconnection should be followed.

1.    When arriving at the incident, turn on the GLM MINI to the high sensitivity setting.

2.    Press and hold the self test button and an audible repeating tone will be heard indicating a healthy unit.

3.    Place thumb and hand as indicated on unit with arm outstretched as the position of your hand and body determines the sensitivity of the unit. In this position maximum sensitivity is achieved.

4.    Identify the main power supply line on the street and access point to the property checking for damage to these lines and clearance levels.

5.    With arm outstretched hold the detector over your head and trace power from street supply to property connection.

6.    If the RED LED indicates and alarm sounds a voltage is detected.

7.    Isolation protocol should now be followed. Contact the local supply authority for disconnection of power supply.

8.    On notification from supply authority that the power has been isolated retest the area again placing the unit on high with thumb on bottom of unit and follow the above steps

When circumstances require access to the property before power has been disconnected use the GLM MINI to determine live power areas. Examples of the areas are:

Placing a metal ladder against the metal gutter

·         Use procedures above for the activation of the GLM MINI.

·         As we know the power to the property is active, place the unit on high and test against conductive components.

·         If voltage detected switch to low setting on the unit and aim at conductive components moving closer. When within 100mm and no AC voltage is detected, the ladder and gutter are not active.

·         The ladder may be insulated from the ground by rubber feet and may not show active. By placing a hand on the ladder a circuit is made to ground through you resulting in electrocution.

·         It is highly recommended to not attach metal items to exterior of property until supply to property has been disconnected.

Upon entering a property

·         Use above procedures for the activation of the GLM MINI.

·         Enter the property holding the GLM MINI with thumb on indicated area and arm outstretched and the unit set on the high setting, if property disconnected no signal should be detected.

·         If voltage detected and the property disconnected by supply authority place the unit on the low setting and move around room to determine where voltage is located.

·         Have trained personnel isolate or disconnect source.

NOTE: Because the property is still live the high setting on the GLM MINI may be detecting other voltage sources such as wires in the roof or walls or the adjacent property. To overcome this use the low setting on the detector and more accurate location of AC voltage sources can be determined. By placing your hand in the middle of the unit not covering the front test area label, sensitivity is decreased providing an accurate location of voltage.

Important Safety Concern

The voltage to a property may be officially disconnected by supply authority. This may not always be the case as faults in the electrical network may cause residual voltages to be carried in water pipes and neutral link connections. Suspect locations such as those involving drugs may be acquiring power from neighbouring locations or generator units these supplies may not be disconnected. These voltages may be low but the current high. Use the GLM MINI to verify voltage at all instances.

Switch Yards & Transformers

1.    In the incidences above contact the supply authority immediately for disconnection and isolation procedures.

2.    When arriving at the incidence, turn on the GLM MINI to the high sensitivity setting.

3.    Press and hold the self test button and an audible repeating tone will be heard indicating a healthy unit.

4.    Place thumb and hand as indicated on unit with arm outstretched as the position of your hand and body determines the sensitivity of the unit. In this position maximum sensitivity is achieved.

5.    Test the area surrounding the switch yard or transformer to detect fallen lines and leaking oil.Note: oil is a conductor stay clear.

6.    If the RED indicator and alarm sounds a voltage is detected.

7.    Isolation protocol should now be followed.

8.    On notification from supply authority power has been isolated retest the area again placing the unit on high with thumb on bottom of unit and follow the above steps.

Identification of underground (URD) test points

Structures such as these contain voltage sources and can be detected by the GLM MINI using the above procedures.

GL McGavin Pty. Ltd. Is a company that was formed in Sydney Australia in 1968, out of a need to protect electrical workers from being injured. With its state of the art product the first of many models of the Modiewark non-contact voltage detector were designed. The Australian power industry gratefully accepted this tester as a life saving device, implementing a national roll out in the early 1970’s.

From this point the Modiewark adapted it’s self to the needs of the industry, improving itself by providing self testing capabilities, voltage selectors to suit each application and accessories to perform substation spout testing and phase compatibility testing.

In 2004 the Morris family Darrell & Norma Morris (owner directors) and their sons Ashley & Linsey Morris (directors) of the Morris Group, took ownership of the company and by consolidating its operation in Newcastle New South Wales, Australia, developed long overdue improvements in its manufacturing techniques. Providing in house quality control on all construction processes, making the product a safer and more reliable test instrument. With the aid of their experience staff the product improved to include phase identification, spout testing application and water resistance devices.

In 2007 a team association with a local engineer and developed a new product line of Modiewarks, The Modiewark Mini Testers providing a miniature and user friendly product allowing us to keep pace with the changing industry. Rescue departments in New South Wales Australia, took up the new rescue tester, providing their staff with a safe approach procedure. The Mini SWER and Pole tester taken in hand by Country Energy for the testing of SWER(single wire earth return) and the application of pole leakage detection which costs the industry many thousands of dollars per year. The MR tester (Meter Reader) was developed to ensure the safety of the meter readers who frequently come across live domestic power boxes.

To ensure quality control with this safety device Pritchard Electronics became an acquisition of the Morris group providing improved technologies and in house quality control.

With new technology on the way the goal of GL McGavin and its staff is to keep pace with the current industry standards and provide a better solution for electrical safety in the future. As one of the oldest and most reliable tester on the market today the GL McGavin Modiewark range of testers will always assist the electrical industry in all electrical hazard safety applications
