We produce a range of High Voltage Proof Test Instruments and various safety devices for the Cable Test Industry.
SURGE GENERATORS
Surge Generators are produced in a range from 5kV to 32kV with discharge energy ranging from 500 Joules to 2000 Joules. Combination Systems are available that enables the user to Pre-Locate high resistance faults.
GROUND MICROPHONE SYSTEMS
Ground Microphone Systems are available in a basic analogue and a high end digital range. In the higher end systems selectable filters and time of flight measurements are standard features.
FAULT PRE-LOCATION SCOPES
Fault Pre-Location scopes are used to pre determine the distance to a fault. It analyses the impedance of the cable using TDR technology. To pre-locate high resistance fault, the unit is connected to the HT pulse, which temporarily lowers the fault resistance.
CABLE SHEATH FAULT LOCATION
Sheath Fault Locators are used to determine the integrity of cable sheaths. The “Pool of Potential” method is used to “Pin-Point” where tiny holes are present in the cable sheath.
PROOF AND DIAGNOSTICS TEST EQUIPMENT
We produce various different models of Electrical Proof Test Equipment. AC, DC and VLF Systems are available for any voltage up to 200KV.
AC SYSTEMS
Alternating Current Proof Testers are used to test busbars, switchgear, transformers and a large array of different objects for electrical integrity.
DC SYSTEMS
Direct Current Proof Testers are used to test certain cable types, for example, Paper Insulated Lead Cables. It is generally used where large capacitive loads are to be tested.
VLF SYSTEMS
Very Low Frequency Systems are used to test special cable types, for example, XLPE, where DC Systems may damage the solid composite insulation of the cable.
AC/DC SYSTEMS
Combination systems are produced with the Test Engineer in mind that has to perform different tests in different electrical environments. Some units simply switch between AC/DC and in some cases it is simple as fitting a diode to the circuit.
SAFETY SYSTEMS
We offer a range of safety devices for the electrical test industry. Cable identification and Cable Spiking Systems are an integral part of the safe test environment.
CABLE IDENTIFICATION SYSTEMS
The Adret range of Cable Identification systems are designed to positively identify any chosen cable from a bundle.
CUSTOM MADE TEST VANS AND MOBILE LABS
Due to the sensitivity of expensive test equipment it is preferred to permanently mount these units in a trailer or panel van. The equipment can thus be protected from mechanical shock. Various Cable Reel systems are available. Our systems utilize our unique magnetic brake system.
TEST EQUIPMENT TROLLEYS
The range is complemented with our custom made trolleys.
TEST VANS
Due to the diversity of test equipment used by our base of customers we produce a number of custom made test van layouts. Customers are not stuck with existing designs.
MOBILE TEST TRAILERS
Some customers prefer Test Trailers when they have access problems into buildings, or when dedicated vehicles are not available.
MOBILE TEST LABORATORIES
We are capable of retrofitting any existing test equipment of any type, with or without on- board power supplies.
