DC testing has been accepted for many years as the standard field method for performing high-voltage tests on cable insulation systems. Whenever DC testing is performed, full consideration should be given to the fact that steady-state direct voltage creates within the insulation systems an electrical field determined by the geometry and conductance of the insulation, whereas under service conditions, alternating voltage creates an electric field determined chiefly by the geometry and dielectric constant (or capacitance) of the insulation.
Under ideal, homogeneously uniform insulation conditions, the mathematical formulas governing the steady-state stress distribution within the cable insulation are of the same form for DC and for AC, resulting incomparable relative values; however, should the cable insulation contain defects in which either the conductivity or the dielectric constant assume values significantly different from those in the bulk of the insulation,the electric stress distribution obtained with direct voltage will no longer correspond to that obtained with alternating voltage.
7SJ62 Multifunction Over Current Protection Relayashwini reliserv
The SIPROTEC 4 7SJ62 relays can be used for line protection of high and medium voltage networks with earthed (grounded), low-resistance earthed, isolated or compensated neutral point. With regard to motor protection, the SIPROTEC 4 7SJ62 is suitable for asynchronous machines of all sizes. The relay performs all functions of backup protection supplementary to transformer differential protection. 7SJ62 is featuring the "flexible protection functions". Up to 20 protection functions can be added according to individual requirements. Thus, for example, a rate-of-frequency-change protection or reverse power protection can be implemented.

Isolation Procedures for Safe Working on Electrical Systems and Equipment by the JIB | solation Procedures for Safe Working on Electrical Systems and Equipment
This chart shows the safe isolation procedure that you should use when working on electrical systems and equipment.
You'll receive a printed copy of this from your Training Provider, but it's also here as a handy reference to keep electronically.
THE RULES OF SAFE ISOLATION ARE:
Obtain permission to start work (a Permit may be required in some situations)
Identify the source(s) of supply using an approved voltage indicator or test lamp
Prove that the approved voltage indicator or test lamp is functioning correctly
Isolate the supply(s)
Secure the isolation
Prove the system/equipment is DEAD using an approved voltage indicator or test lamp
Prove that the approved voltage indicator or test lamp is functioning correctly
Put up warning signs to tell other people that the electrical installation has been isolated
Once the system/equipment is proved DEAD, work can begin

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Description
The TPU 4x.xx transformers are cast in epoxy resin and designed for insulation voltages up to 12 kV. The 3,6 kV and 7,2
kV versions have the same dimensions as the 12 kV.
For certain types of panels there is a need for extra long
creepage distance on the transformers. For this purpose you
can order current transformers with „ribs on the top”.
The transformers are manufactured in conformity with dimensions stated hereunder. The TPU4x.xx transformers are
designed as single-turn or multi-turn versions, with one transformer ratio or with double ratio having the possibility to be
reconnectable on the primary or on the secondary side.
The number of secondary windings (from 1 to 6 – max. 12
secondary terminals - 2 rows), depends on the combination of
the technical parameters (such as the accuracy class, burden,
short-circuit current, overcurrent factor…) and the transformer
dimensions size.
When agreed between the manufacturer and the customer the
TPU transformers can be provided with the voltage indication
system. For this purpose, however, it is necessary to know in
what insulation level the transformers shall operate.
The secondary windings are used for measurement or protection purposes, or for special use (testing winding, „X” class
windings). One terminal of each secondary winding used
and one terminal of short-circuited and not used winding have to be earth during the transformer operation. The
secondary windings are lead out into a cast-type secondary
terminal box with plastic cover. The terminal cover is sealable.
The terminals are provided with M5 screws for the termination and with throughgoing holes for direct earting (first row of
secondary terminals)
Technical data
The transformer can be mounted in any position. The
transformer body is fixed by using four screws. Earth clamp
M8 is on the transformer base plate.
Rated primary voltages are 3.6 kV; 7.2 kV; 12 kV
Rated primary currents are 10;15;20;25;30;40;50;60;75;100;
150;200;300;400;500;600; 750;1000;1250;1500;2000;2500;
3000 and 3200 A;
primary reconnectable modification max till 400-800 A.
Other primary currents can also be agreed upon with the
customer.
Rated secondary currents...5 A; 1 A , others on request
(possibility to combine different values in one transformer)
