Page 7: Description Of Equipment
DESCRIPTION OF EQUIPMENT Electrical Specification Output Voltage Control Overload Protection Metering Automatic Earthing Manual Earthing Using DP40 Discharge/Earthing Probe High Voltage Output Cables Construction... - Page 9 Electrical Specification 1.1.1 The supply voltage for the equipment is 240/220/115V, single phase, 50/60Hz. Each input will tolerate the following voltage variation: 240V +/- 10% 220V +/- 10% 115V +10% and -6% 1.1.2 The maximum power supply requirements will be 750VA. 1.1.3 The output voltages which are continuously obtainable from the equipment are as follows:...
- Page 10 Output Voltage Control 1.2.1 The output from the equipment is controlled from zero by means of a regulating transformer. 1.2.2 The regulating transformer is operated by means of a control knob which is located on the right hand side of the instrument's front panel. 1.2.3 To increase the output voltage turn the control knob in a clockwise direction.
- Page 11 Overload Protection 1.3.1 The instrument is fitted with a fast acting fuse which protects the incoming mains supply to the unit. The rating of the fuse is as follows: F 5amp for 240V/220V/115V operation 1.3.2 The outputs from the instrument are protected by means of a fast acting magnetic overload relay which in turn controls an output contactor.
- Page 12 Metering 1.4.1 The equipment is fitted with two output kilovoltmeters, which sense both the positive and negative outputs simultaneously. Both instruments have a single range of 0-30 kilovolts. Each division on the instruments represent 1 kilovolt. The individual meters are captioned as follows: Positive kilovoltmeter: + kV DC (In red)
- Page 13 Automatic Earthing 1.5.1 AUTOMATIC DISCHARGE/EARTHING The automatic discharge system, which is fail safe, will discharge a maximum of 2.5 kilojoules at 30kV DC four times every hour. The contact surfaces of the internal dump switches are made of very hard dissimilar metals to contain contact burning and erosion.

- Page 15 The high voltage plug is protected in transit by a plastic cover. The plastic cover is attached to output cable by means of thick nylon cord. 1.7.3. The high voltage plugs used on the PT30-10 are fully de-mountable, thus allowing for retermination on site should the output cables become damaged.
- Page 16 Construction 1.6.1. The PT30-10 is housed in a robust case consisting of a rigid frame construction with removable side covers to provide good access and serviceability. 1.6.2. All the controls are located on the equipment's front panel, together with all input and output connections.

- Page 19 Remove and rotate fuse carrier until desired supply voltage is seen through the fuse drawer window. The PT30-10 is suitable for 3 different supply voltages as follows: 240V/220V or 115V. Replace fuse drawer once the desired voltage has been selected.
- Page 20 Front Panel Control Functions 2.2.1 ITEM FUNCTION Supply ON/OFF key switch To isolate both supply leads from the mains supply . Also to prevent unauthorised operation of the equipment when the key is removed Supply ON lamp To indicate that the key switch is (RED) closed thus connecting the equipment to the supply.

- Page 23 Observe the slow decay in the output voltage which will indicate a healthy cable. After 30 seconds switch off the HV output. The PT30-10 has an auto- earth system which will discharge the cable. Using the discharge/earthing probe tip discharge any remaining charge on the cable, then connect the earthing hook on to the test terminal.
