1 TRANSFORMER TEST VAN TransLAB-2 The transformer test van TransLAB-2 performs the following: 1. Capacitance and tan delta measurement of high voltage insulation by the direct and inverted setups 2. Low-voltage measurements of power and instrument transformers 3. Measurement of the windings resistance of single and three phase transformers, motors and other equipment Functions of TransLAB -2: Capacitance and tan delta measurement of high voltage insulation by the direct and inverted setups Low-voltage measurements of single and three phase transformers Turns ratio test with a single-phase excitation Turns ratio test with a three-phase excitation Current measurement and no-load losses at low voltage Voltage, current and resistance measurements with a short circuit test Measurement of low DC resistance Insulation resistance testing by using high voltages up to 5 kv Measurement of the windings resistance of single and three phase transformers, motors and other equipment

2 Technical Specifications of TransLAB -2 Parameters Description 1. Power supply voltage 3 phase, 50HZ, V 220±22 380±38 2. Max. Input power, kva Module parameters of low voltage measurements Range of adjustable output AC, V Maximum output current, А 52( at voltage V) 40(at voltage V) 4. Parameters IDP-10М: - measuring range of capacity Сх 10pF 340nF - measuring range of tangent delta 1х10 5 1,0 - fundamental error of measurement %, no more than Сх tgδ ±(0,5+0,005Сх) ±( ,01 tgδ) To create a symmetrical voltage measurement, three voltage regulators and three load transformers are being used. This is achieved by connecting to the structure of the low voltage measurement module 3 load transformers with a power of 20 kva. The design of the TransLAB-2 is unique in the current market designs by the following characteristics: 1. Availability of a powerful symmetrical three phase power system 2. Availability of remote voltage control 3. Capability of integrating the laboratory with different load transformers (4 kva, 13 kva, or 20kVA and with voltage up to 500V), according to the needs of users 4. Capability of performing diagnosis and testing of power transformers of different power and sizes All equipment of the TransLAB-2 is installed in the cargo body of a commercial van The body is divided into two compartments by a partition wall: Operator compartment; High voltage compartment

3 Main Equipment In the high voltage compartment the following devices and units are located: Ground control module Module of high voltage devices for measuring tgδ MVP 10, which includes a switch for performing measurements, a power converter meter of insulation «TANGENT- 2000» and a high voltage transformer for measuring the insulation«tangent-2000» Cable reel with a measuring shielded cable (cable supplied with the Tangent 2000) Cable reel with a measuring cable (cable supplied with the Tangent 2000) Load transformer ТНМ20-220/ pcs Voltage regulator 3 pcs Cable drums module: cable drums with power cable cable drums for low voltage measurements cable drum with protective grounding cable In the operator compartment the following are located: Laboratory control panel with input divider, electro automatic elements, controls and monitoring indicators Insulation parameters measuring unit «TANGENT-2000»

4 Operator working area Drawers for storage of accessories Laboratory Interior Design The transformer test van is designed to be easy to operate and service. It is equipped with high quality insulated wall panelling and air conditioning. The body is divided into technical and operator compartments separated by a partition wall. The technical compartment includes all the necessary tools and equipment for carrying out testing and inspections. Safety is an important feature of the laboratories and hence all equipment is properly mounted and secured for transit. The operator compartment provides a pleasant environment to work in with more room and plenty of storage. It is equipped with cabinetry and workbenches that increase the operators efficiency and productivity. Features Air conditioner Internal lighting 230 VAC & 12V DC Insulated walls and roof for thermal and noise Special antistatic floor in operator area Special aluminium tread plate suitable for rough loading in technical area

5 Partition wall between operator and high voltage compartments Operating desk & swivel chair Drawers for storage of accessories The laboratory has an advanced managing and control system which provides automatic measurements and safety of personnel: 1. In the case of absence or disappearance of the supply voltage, the lighting circuits are automatically connected to the vehicle battery 2. In conditions of voltage excess in the circuit ground above 25V, the laboratory will be disabled automatically 3. Under turning On and Off the high voltage sources, a siren automatically sounds, which is installed outside of the body of the laboratory 4. During measurements on low voltage mode, a light signal automatically turns on, which is installed outside of the operator compartment Vehicle Chassis: IVECO DAILY, MERCEDES SPRINTER, FIAT DUCATO ETC. The basic types of chassis used are: Mercedes Sprinter, Iveco Daily, Fiat Ducato, Volkswagen Crafter etc.
