Electricfield Oil Test is designed for testing strength of Insulating oil. The sets are available for 0-60KV and 0-100KV voltage range in manual as well as motorized for uniform rise of voltage for noticing correct break down voltage. Electricfield Primary Injection Set is intended to carry out the testing after completion of installation especially if the protective gear is connected to the power line via a current transformer. Electricfield make Secondary Injection Testing Set is portable equipment suitable for testing of all types of over current and earth fault relay of 5 amps secondary or 1 amp secondary current. The test set is designed to provide evenly controlled current output as per the requirement. The set is complete with a standard oil test cell, a transparent cover with any live part. The set conforms to IS: 6972/1992 EC 156 etc. A tripping circuit is provided in the set to disconnec the voltage to step-up H.V transformer in the event of break down of sample instantaneously. A voltmeter to indicate visually actual test voltage is so connected that the break down voltage can be read even after the breakdown of oil sample. The test operates at input supply of 230V, single-phase 50HZ.
Electricfield oil testing equipments came in two sets :
1. Electricfield Primary Injection Set
Electricfield Primary Injection Set is intended to carry out the testing after compleion of installation especially if the protective gear is connected to the power line via a current transformer. A suitable current is injected to the power line, which provides an over all test of the current transformer and the protective devices. In view of intial testing after completion of installation, it is not sufficient to assume that it will control and isolate any fault condition that may arise after considerable period of time. When such devices are called upon to operate, they may fail to function due to having been in service for long period with little or no maintenance, resulting in tripping mechanism becoming faulty or even broken. The test set operates on single-phase supply of 230V AC 50Hz consisting of ammeter to record load current variac capacity as per output load and step down transformer as per the requirement.A part from its use for the above application it can be used as primary current to C.T testing and testing of various other protective devices meant for motor protection, MCCSs and ACBs.
2. Electricfield Secondary Injection Set
Electricfield Secondary Injection Set is a portable equipment suitable for testing of all types of over current and earth fault relay of 5 amps secondary or 1 amp secondary current. The test set is designed to provide evenly controlled current output as per the requirement. The set is so designed hat its output is unaffected by relay burden. The current output can be modified to individual requirement. The test set can be used for number of other applications where controlled AC supply of good waveform is needed. The testing set incorporated time interval meter for recording the time while testing the equipment.
